Someone who is funny, but incredibly selfish and a huge asshole. Has very low standards and doesn't know how to treat a girl right because he's too busy thinking about himself and weed. A bit repulsive.
"Wow, he's funny, but he banged that fat ugly girl, he must be a Henry."
" That guy is disgusting! He's such a Henry!"
" Wow he smells nasty, like weed. And he is such an asshole to his girlfriend!He must be a Henry!"
