look up any word, like bukkake:
When a man mounts a bare or clothed female from the top, with his penis resting between her breasts poiting towards the females lower body, undulates with the intent of producing an orgasm. If the man also receives a butthole lick job from the lucky lady, it is called a "dirty Morberg".
Bro, did you Morberg that shirt?

Fuck yea, ass in face, dick down the blouse!
