look up any word, like donkey punch:
 
1.
Someone that hangs out regularly at the gym on league night hoping to get picked up on a team. He hopes for no-shows, injuries, does not contribute league dues, and is argumentative despite the fact that he is not a member of any team.
Teammate 1: Doug hurt his back again so we're short one tonight. The guy that subbed in for us last week is over there.
Teammate 2: He got pissed off and argued alot. You wanna pick him up again??
Teammate 3: Nah, I'd rather play a man short than play with that substidouche.

Also correct to use as a proper noun:
Teammate 3: I'd rather not play with Substidouche again.
