A plug is a hockey
player than sits in the press box most nights. They only make their
way into the lineup when several injuries occur, leaving the coach with no other choices. The
player is “plugged” into the lineup.
Richard: “Damn, dude, did you hear that Melvin and
Marvin are both hurt and can’t play tonight?
Murphy: “Yeah I saw that
shit. Now Philly and Dill are lacing them up tonight. Those guys are such plugs. We’re fucked!”
