Former NHL player Daniel Carcillo -- a Stanley Cup winner -- claims he was terrorized and sexually hazed during his time in junior hockey ... and now, he's suing over it.
Carcillo, in a new lawsuit filed in Toronto, alleges that when he was in the Ontario Hockey League -- one of the 3 major leagues that make up the Canadian Hockey League -- he was violently hazed on a daily basis.
In the docs, obtained by TMZ Sports, 35-year-old Carcillo says he was peed and spat on by veterans, smacked in the bare butt by a sawed-off goalie stick, and also forced to attend and participate in sex orgy parties.
