Bumtash 

The game where, whilst having sex with a woman doggy style, you wipe your finger across your poo stained arse and wipe it on their top lip. The idea being to hold on as long as possible before you get thrown off. Extra points for blarting first.

Donald lasted 25 seconds when he bumtashed Mandy.
