For example, I’ve been rewatching some Psych lately, and saw one yesterday with “Lewd” Imman Phillips. And whenever I think of the specific actors in question, I think of “Loofa” Rigno and James “Gandolf” Feeny, for example.
Come buy your next car at Harrison Ford. Exit 6 off the Interstate.
I can’t stop referring to him as “Crisp Rat” ever since I saw it posted on Facebook a while back.
Him who?
Antecedents can be your friends.
I would have thought it was obvious. Read it out loud. 
Yeah, that’s a good one.
Ah, got it. I just don’t read posts out loud.
Maybe I’ll have to start, that was good.
The man who played Wolverine is forever Huge Ackman to me.
Benodoctor Cucumberpatch has never been referred to by his real name in my hearing or when I’ve see him referred to by friends online. The names vary, but it’s never whatever his real name is supposed to be, whatever that is.
I made up nicknames for almost all of the actors on Criminal Minds.
Gobbler - Gubler
Vagueness - Vangsness
Joe Montana - Joe Mantegna
Honk, Honk, Honk - Tripplehorn
L-o-l-a, Lola - Lola
And so forth.
My father passed away 40 years ago, when I was ten, but I still remember he would sometimes mention some actor named “Marlon Branflakes.”
I’ve posted this here before; as a child I thought Cloris Leachman’s name was “Clorox Bleachman”. My brother and I still call her that.
Not an actor, but John Cougar Watermelon Camp.
In my mind, he’s John Camp Cougarmelon.
My father invariably referred to Don Rickles as Don Wrinkles.
I’m fond of referring to WWE’s Brock Lesnar and Braun Strowman as BORK LASER and BROWN STRONGMAN respectively.
Years back my brother used to refer to Don Johnson as Dumb Johnson because he found the plots and premise of Miami Vice to be ludicrous.
there used to be an advertising poster up in the laundromat I used decades ago with jokes and cartoons on it. It had two cartoons next to each other – John Cougar’s Melon Camp and John Melon’s Cougar Camp. the cartoons showed cougars and melons cavorting in different camp activities – volleyball, swings, etc.
I’ve always thought it was “Chlorine Bleachman” ('cuz there ARE other brands of laundry whitening products, and “Chlorine” sounds more girly anyway).
The new posts are straying from the intended purpose, in that the nickname is pronounced identically or very nearly so to the real name with the difference only showing up in written form.
