Lifeguard we named Pokey because he seemed to have a permanent hardon.
Greasy Middle-Aged Lotto People-Watcher Guy. I bought $5 in MegaMillions tix yesterday (hey, no withering looks, please – the pot had hit $200 million, with odds of winning 1 in 77 million, so in my book that’s a relatively good buy) and there was a guy just sitting there, in front of the payment counter, watching the people come and go…
Thing was, I could have sworn I’ve seen him there before. Like, maybe a year ago, when I last bought a few Lotto tickets… 
Of course, from his point of view I would be Stingy Opportunistic Huge-Jackpot-Only Lotto Buyer Woman. 
The O-holes - the neighbors who live behind us. Father’s name started with an O - my DH called him Mr. O, so the family is now the O-holes, but could in reality be called another kind of hole… 
Pineapple - my DH nicknamed one of the elder O-hole daughters.
Rabbit Turd - Pineapple’s former live in boyfriend. When he moved in shortly after Pineapple kicked out her last lover/hubby/whatever, Rabbit Turd was the only one who would clean out the rabbit’s cage and take care of them. Actually, he seemed like a somewhat decent guy.
Mr. Pony Tail - the latest of Pineapple’s live in lovers. Has a very long pony tail. Overheard the other day from Mr. Pony Tail as he was talking to someone visiting them - “Did you just get out of jail?”
The Killer - another of the elder O-hole daughters. She shot her ex-hubby/ex-lover six times point blank in the chest - said it was self-defense. Only did 18 months in prison.
RE - the O’holes - almost all of their adult children have moved back in with them. Mr. O passed away a few years ago. So, its just Mrs. O and the daughters and a son or two. None of these children (who are well over 40 years old) can manage on their own.
Mr. Green Shirt - a guy that lives up the street that visits our next door neighbor. Mr. Green Shirt seems to own only one green t-shirt.
Nicky the Dicky - 20 something year old girl across the street, who when in high school, used to play hooky (and a few other things - LOL) and “sneak” numerous boys in the house during the day when her parents were at work.
D-Doll - next door neighbor. She’s actually a very nice person. Lives alone. Doesn’t seem to have ever had a boyfriend. My DH insists she has an inflatable male doll to fulfill her needs. LOL
A group of us ride on a commuter train together in the afternoon. We nicknamed this one “odd” kind of out of place guy “Cooler Man” because he always carried a cooler around. We used to have lengthy conversations when he wasn’t around as to what the contents of the cooler were - various body parts, bones, brains, weapons, ammo. He was the guy you’d imagine going “postal” if ever there was one. He once told someone he bought a new bike but wouldn’t ride it until he installed a gun rack on it!
Someone finally had the nerve to ask Cooler Man what was in his cooler - Pepsi’s and Rice Crispies cakes. Those two items were certainly never on our “potential contents list”.
Cooler Man took another job and no longer rides our train. We always tried to not say Cooler Man when he was around, but evidently he heard it and realized it was in reference to him. On his last day on the train he said “There wont be any more Cooler Man on the train”… I about died when he said that!
Walkin’ Man seems to be a pretty common name; we have one around here. He’s at least 6’2" and 350 lbs., has a bushy beard and a walking stick. We’ve seen him around for years, always walking, but he never seems to get any lighter.
There’s a guy in the neighborhood we refer to as Here Max because he always takes his dog (Max) out for a walk without a leash and ends up walking all over the neighborhood calling for him.
Then there are The Royals that used to live down the road. They had three kids whose names were William, Victoria, and Edward.
I usually just call them all Scooter.
Pain in the Butt Lady: I heard this one from a friend I was walking around the neighborhood with; she said that this lady constantly called the police just to make petty complaints about her neighbors, as if she had nothing else to do.
There’s a rotund old man who stands outside his garden in my little town and watches traffic go by every day. He must stand out there for about 2 hours a day, just watching the cars go by his house. Due to his very sperical belly and spherical head, my wife and I call him “The Weeble.”
Hey honey…was the The Weeble out today?
Yes, dear.
The Chin - The guy who lived a few apartments down and had not only a very strong jaw line, but a Kirk Douglas dimple as well.
Hod the Bod - We actual knew his name from his mailbox (Hod? What kind of last name is that?). He had the most incredible physique either my wife or I had ever seen. “Susan! Quick, Hod the Bod’s hanging out clothes again!”
Pony Boy - A member of my gym who has a very, very large schlong.
Commander McBragg - We knew his real name, but he was so prone to telling such outrageous stories about himself that we never used it.
The Mayan - Another neighbor that had a sort of sloping forehead and prominent nose. His profile looked just like something you would see carved into a Mayan ruin.
Aquaman - I don’t think I’ve ever seen this guy without a bottle of water in his hand.
Outside Baby : A baby boy whose dad says that he fusses in the evening because he wants to go outside in his stroller for a while. My walking partner now refers to him by this name.
These evening walks have been good fodder for us.
