Pignudging is the act of lifting, or nudging aside, the
small,
pig-like buttocks of a female with an over-sized
arse in order to engage in doggy-style sex.
Man 1 - I was having sex with this girl last
night and her
arse cheeks were so
big I had to move them aside to get in.
Man 2 - Ha, ha, you pignudger, you.
