While your bangin' a phat chick in the tailpipe on a balcony, you pour orange paint all over her rolls, shout "FIRE IN THE HOLE", then punt her ass off.
After I was done seedin' this plumper's patch, I gave her the ol' pumpkin chunkin'.

Get the Pumpkin Chunkin' mug.
The act of having a sexual act "doggy style" and then putting a hollowed out pumpkin on the recipient of the "doggy style". Then once the recipient looks like that sleepy hallow dude, one humps the monster through a wall. Thus the pumpkin chunk.
