Bucking
Rogering someone that the Bucker considers to be a complete and utter bastard, usually anally and with an inanimate - or animate if the occasion calls for it - object.
Man 1: I've just had a thought.  Let's buck Matthew Caris with a jar of marmalade.
Man 2: Yes, his crack is big enough! Let's go!
