shoulder devil
A person you hang with who is a real bad influence. Pushes you to do immoral things. Talks you into doing things you know you shouldn't, but seem real good at the time. Preys on temptation usually just to sit back and watch the outcome. Much like the devil/angel in the cartoons.
"Just take it, it won't hurt you. I swear it'll be fun. You'll have the time of your life" Luke said to me. He's such a shoulder devil.
