Hulk complex

When someone acts alpha/aggressive/rude dismissive etc. to most people outside of romantic/family relationships. Much like how Hulk only calms down around Betty Ross, someone with a Hulk complex only shows their vulnerable selves with a small number of specific people (ie girlfriend/wife).

Jack is so mean to me, but I never did anything to him.
Nah dude, it's not you. He's got a Hulk complex. I've seen him give his gf Eskimo kisses in the car.
