A pussysider is a guy who jumps into an argument between a man and a woman ----and as you can imagine by the name ----sides with the woman. The pussysider does this regardless if the woman's side in the debate is riddled with faulty logic, conclusions etc. He does this in the hope of getting pussy from his show of support. However, the pussysider never gets pussy. This makes his jumping in completely asinine.
Dude get out of this debate you pussysider, you aren't going to bang her by backing her up, dipshit.
