My sisters and I invented the word “woogy”, meaning “of or pertaining to our dog, Snowball” a creature who is otherwise pretty undescribable. When I was in elementary school, I tried to invent a new word for really cool: “dudical”. It did not catch on. In later life, I became well known for coining new terms on the spot, as needed. I have forgotten most of these. The only exception is when somebody criticized me for this habit. Did I get defensive? Angry? Hot under the collar? No! I simply replied “That’s right, I’m a logonuminator!” They went away, leaving the field to me. Also, I have a friend who refers to the microwave oven as a- and this cracks me up every time- nuclywave. Anyway, bye for now, gotta, uh, cyberambulate on.
Well Stoid, we just use “Granola” here at my University 
Since childhood, the three of us, my brother, sister, and I, have used “chop,” meaning a good putdown or a squelch.
For example: an item I clipped from *Mad *once about a customer in a French restaurant.
Waiter (French accent): Monsieur, you are having trou-bull? May I help?
Customer: Yes! This menu seems to be printed in a foreign language and I can’t understand it.
Waiter. Oh yes! This is an authentic Fransh restaurant! The cuisine, the décor, the ambience, are in French! Everysing here is en français!
Customer: Great! Then I’ll pay the bill in some authentic French money I have left over from my European trip!
Waiter (in harsh Brooklyn accent): ARE YOU OUT OF YOUR COTTON-PICKIN’ MIND???!!!
In the last panel I drew a thought balloon over the smirking customer, reading: “What a chop!”

Someone in my group of friends at college invented the word “quiggan” as a name for those little plastic containers of coffee creamer you get at restaurants. My dh and I still call them quiggans.
Squabbit: It’s a combination of squirrel and rabbit. The woods behind my girlfriend’s house are full of squirrels and rabbits and I picked it up from her family. Now I catch myself using it in conversation with other people, and needless to say getting some really weird reactions.
A few from my household-
Squidgy- covered with dog spit/slime
We had a toy frisbee for our Rott that said “Squidgy Disk” on it that would get totally slimy from him chewing it, so the name stuck.
Here’s a few from childhood- don’t know if they’re made up from my parents or real words. Let me know if anyone has heard them…
Poochies (pronounced “puch”, not “pooch”)
a pair of slippers. My whole family says this.
A Blivit - (You look like a blivit)or (I feel like a blivit)- 10lbs of shit in a 5lb bag.
Yaga Bag- a mesh like bag for carrying stuff. (This is a Mom ism…)
Anyone recognize these words??
Run for the hills, folks! Or you’ll be up to your armpits in martians!
Instead of saying OB/GYN, which always sounds hacked up, I call this doctor and **Obstecologist ** It has a nicer flow to it.
When I was little and my mom put my hair up in a ponytail, I called those lumpy spots that never lay down right “rumples”.
Diana, as for “toot” I used to use that one too, but we were usually tooting up our schnozzes. <sighs at days gone by>
When my daughter was one year old, I started to call her Shnotsky…I suppose it was an aftermath of her flu…=). The name stuck, she is six now…

well, let’s see…I came up with “wiseassery” about three weeks ago, as a term for what I’m really good at. I just like the sound of it.
“Krang”- 1. v. to get smacked down at something. 2. n. a sound effect simular to “crash”
“Dar” - Simular to the phrase “As if”, this is a stand alone exclamation I use in response to an idiot or an idiotic saying or event. Genrally the “a” is stretched for dramitic effect. “Daaaarrrr!” (I got this one from the title character’s name in Beastmaster.)
“Goatknocker”- Do I really have to explain this one?
You say “cheesy” like that’s a BAD thing.
Although I didnt make it up, I really enjoy saying the word ‘linoleum’ out loud. 8^)
