Brain Blast

When a woman gives head and before you nut on her face you pull her head down on your dick so you bust up her nose into her brain.

Brain Blast

A brain blast is when you go in for brain surgery and while the doctor has your head cut open, ejaculates into your brain.
Also when you shove your penis so far up someone's nose and jizz, it touches their brain.

I went in to get brain surgery and when I woke up I realized I had a brain blast!

Brain Blast

1. Performing oral sex, or "face fucking" so roughly that when ejaculating semen spews out of both mouth, nose and (never has been confirmed) ears. First originating from Old English, and made more known when Jimmy Neutron coined the term.

2. Ejaculating in the mouth , but then continuing to have vaginal or anal sex. Where as to when finishing in the selected hole, the person getting "Brain Blasted" coughs up the semen left in the mouth the exact time you finish in the ass or vagina.
