This character was more really annoying than weird. Not one of my characters, and this was a long time ago, but...
When I was about 14 I was playing in a homebrew campaign run by one of the guys in my group. Most of us were pretty decent players, I mean you know, as 14 year olds we had some pretty silly hijinks and so on going on, but for the most part we liked a good story... However, we had one guy who was the That Guy of our group. Unfortunately, he was also the best friend of the GM and could get away with pretty much anything.
So we're in the middle of the endgame for the current chapter of our campaign, and we're all taking a trouncing from the BBEG. Suddenly That Guy declares that his monk stands up, yells "This looks like a job for Pleasure Man!" and then rips off his monk robes to reveal a superhero outfit... and yes, the character was exactly what he sounds like. All of his abilities revolved around using his *ahem* in some way or another, including ranged attacks.
Not only was he a ridiculously BS character, but the custom abilities that the player and the GM had come up with were so over the top that he managed to destroy the BBEG in a couple of turns, then proceeded to just solo every encounter for the next few sessions.
After that we just ended up reforming a new group minus the GM and That Guy, and moved on from that crap.
