Full Metal Jacket has some golden insults.
Hartman: You are pukes. You're the lowest forms of life on Earth! You're not even human fucking beings! You are nothing but unorganized, grabbastic pieces of amphibian shit!
Hartman: How tall are you, private?
Cowboy: Sir, five foot nine, sir!
Hartman: 5' 9"? I didn't know they stacked shit that high. You tryin' to squeeze an inch in on me somewhere, huh?!?
Cowboy: Sir, no, sir!
Hartman: Bullshit! It looks to me like the best part of you ran down the crack of your mamma's ass and ended up as a brown stain on the mattress! I think you've been cheated! Where in the hell are you from, anyway, private?
Cowboy: Sir, Texas, sir!
Hartman: Holy dogshit! Texas! Only steers and queers come from Texas, Private Cowboy, and you don't much look like a steer to me, so that kinda narrows it down. Do you suck dicks?
Cowboy: Sir, no, sir!
Hartman: Are you a peter pumper?
Cowboy: Sir, no, sir!
Hartman: I'll bet you're the type of guy that would fuck a person in the ass and not even have the goddamn common courtesy to give him a reach around. I'll be watching you!
Hartman: Do you suck dicks?
Pile: Sir, no, sir!
Hartman: Bullshit! I'll bet you could suck a golf ball through a garden hose!
