brain butter 

The mixture of ejaculate and grey matter that is churned as the result of skull fucking.

As Jess got up to go freshen up, an amount of brain butter leaked out of her eye socket. Brian caught it and was able to spread it on an english muffin which he enjoyed on his commute to the office.

a variation of the Angry Dragon. While a woman is performing oral sex on you you plug her nose while you spoolge in her mouth if done correctly it may shoot out her ears. Warning may cause retardation.

When you nail a chick from behind and pull out just as you cum, ejaculating into your hand, and then slapping her in the ear with it.

"Dumb bitch actually believed she was going to get away from me without cum on her face. I gave her a brain buster for complaining."
