Folditis
When its time to go to pound town but either A, she isn't wet enough or B, you aint hard enough. Both scenarios resulting in the same: a pathetic attempt to insert, usually ending up with your semi-hard chub either folding over on itslef or just completely scrunching up like an accordion
Dude last night i was so close to getting it in with Mary but due to either the excess of vodka or the lack of EDM tunes being cranked, I caught a bad case of the folditis
