Before even looking at your links to see if they’re there, I’ll mention a few that popped into my mind when I read your title.
The old Marlon Brando movie One Eyed Jacks which he directed (his only such) and acted in, has quite a few:
“Git up, you big tub of guts.”
“Why you gob of spit.”
“You mention her name one more time and I’m gonna tear your arms out.” (Not so much an insult as just a great line.)
The amazing thing about the movie was that it was made so early in the 60’s that it preceded the relaxation of the language rules where real cussing and foul language could be used with relative impunity. These were pretty harsh for that time.
James Dean had a nice one in Giant: “I’m a rich one, Bick. I’m a rich boy. I’m gonna have more money than you ever thought you’d have. You and all the rest of you stinkin’ sons of Benedict.”
I’m surprised that neither Samuel L. or Robert DeNiro made the cut, not to mention Clancy Brown from Shawshank: “What is your malfunction, you fat barrel of monkey spunk?”, or “You’re gonna look real funny sucking my dick with no teeth.”
In Coal Miner’s Daughter, Sissy Spacek as Loretta Lynn has this little mild exchange with Doo’s Floozy
Floozy: Just who do you think you’re talking to?
Loretta, in that awesome mountain drawl : “Well, *I *don’t know who you are, but I know WHAT you are!”
I didn’t bother staying too long – they weren’t really all that funny or epic, just name calling. I’ve heard the same things by eight year olds on playgrounds.
I much prefer the insults that sneak up on you:
“Why don’t you go home to your wife? Better yet, why don’t I go home to your wife and, outside of the improvement, she’ll never notice the difference.”
“I see you bending over a stove. Only I don’t see the stove.”
“Remember. We’re fighting for this woman’s honor, which is probably more than she ever did.”
