Festerbation

Festerbation is the act of choosing to wallow in escalating sexually longing without any reprieve or sexual release. It is physiologically unhealthy in that it increases stress levels in the individual.

Jill was rejected by Jack. Instead of a revenge fling, Jill fixated miserably on all the great sex they used to have, and "festerbated" herself into a migraine. The migraine was due to extreme "festerbation".

foster funk

When the smell of a fart lingers in a room to create an air freshener like aroma that smells of pig poop that has been basking in the sun all day

Squirt: hey what's that smell?
Steve: you know that Foster Funk.
Squirt: Josh hasn't been in here for a good hour!?!?
Steve: Exactly his foster funk is strong

foster's whirlpool

Sex act in which one takes a can of Foster's Australian lager and a beer bong inserting the hose end into the partners anal cavity and pours the can into the beer bong. The act can include a lego surf guy. Just make sure to tie a string to the surf guy, so you don't have to send the lego diver in after him.

Man, this chick let me do a Foster's whirlpool to her. Yeah. Lost the lego guy though.
