Get the brain mug.
When getting a blowjob, the dick goes so far in it tears the back of the throat and somehow manages to penetrate the brain
Yo dude, this hot chick totally gave me brain the other day! Too bad she died, bro.

Get the Brain mug.
When a male grabs one of his testacles and gently squeezes so that the ball sack is tight around the testicle hence looking like a human brain.
Tom:Gee pat do you know what a brain looks like?
Pat:Why no i don't.
*Tom acts out the definition given*
Tom:Look
Pat:Oh right cool, nice one

Giving head to assess the cognitive strength and abilities of the man.
I gave him the best brain of his life to get the highest cognitive rating.
