look up any word, like bukkake:
 
1.
(n.) plural-whombi. A ball-sack without a penis (nuts without a dick). This can be found in cancer patients or a loser who are not cool enough to have an extra appendage, or an idiot who chopped his dick off. A whombus can also be referred to as a flying whombus, due to its close resemblance of the flying wombat animal. A reverse whombus would then be a penis with no nut-sack. A whombus is a highly hilarious deformity that should be used against a whombus owner regularly. Notable historical figures such as GWB and John Humphrey Noyes were credited with having whombi.
