a 'friendship' based on ass.
different than FWB because in that situation you tend to be friends first then benefits come along. but in an ass-ship, its jst a friendship because of the fact that there is ass.

its almost like that one guy/girl that u never talk to as a friend (like call to hang out or even talk to) but u know that it is an ass-ship cos u can call them up for some chitty chitty bang bang.
-so are you guys friends?
-well we have an ass-ship sorta situation

dude this lack of booty between us is so lame, i barely get to make any calls, what kind of ass-ship is this?
