A friend who when around you belittles you or makes you feel bad about yourself. Someone you hate to be around. Someone who everyone fears, but is still their friend
That Billy Bob is such a Toxic Friend the way he makes fun of me.

a friend that embarasses you in social situations in order to gain attention; a person that constantly betrays your trust, but you cant get away from due to guilt issues; a type of friend that is ok one on one, but will turn on you as soon as other people are around, making it hard to break off the friendship because you 'know how they really are'.
toxic friend: *loudly so that the cute guy standing next to you hears* remember when you ripped that loud fart in front of that guy you liked?
