2. MONTY PYTHON AND THE HOLY GRAIL (1975)

The situation: Atop his castle, the French guard pours scorn on King Arthur and his “silly kerrniggits”, spitting down vitriol like acid rain.
The insult: “I don't wanna talk to you no more, you empty headed, animal food trough wiper. I fart in your general direction. Your mother was a hamster and your father smelt of elderberries.”

1. FULL METAL JACKET (1987)
The insulter: Gunnery Sgt. Hartman (R. Lee Ermey)
The situation: Tubster Private Pyle dares break a smile while having his hair dryed by his furious drill sergeant. What followed were the most brutal, most heartless and most downright hilarious insults in movie history. It’s almost impossible to pick one amongst a tirade that lasts several minutes (“You look like you could suck a golf ball through a garden hose,” “I didn’t know they stacked shit that high,” “Looks to me like the best part of you ran down your momma’s crack and ended up a brown stain on the mattress,” and so on) but pick one we had to…

The situation: The golf pro attempts to give amateur ball-smacker Happy a verbal beatdown, but fails.
The quote: “I eat pieces of shit like you for breakfast.”
Why it sucks: The straight-faced reply of “You eat pieces of shit for breakfast?” leaves Shooter struggling for an adequate response. “No… I…” Man down. Man down.
