he dares or teases you into drinking
does he encourage you to do shots or chug a beer? he's bad news
he takes you away from your friends
when he tries to lead you to an empty room or plays keep-away with your cell, beware
he tries to intimidate you
if he attempts to get you to hook up, by saying," I can have anyone else here," or "I thought you were cool," he's trying to coerce you.
