brain aneurysm 

A masturbatory technique wherein one gets into the shower, turns the hot water on as high as can be withstood, then proceeds to squat down and masturbate furiously. Upon reaching orgasm, stand up and turn the cold water on full blast. If timed right, orgasm will occur at the same moment that icy water pours over you, causing an experience unlike anything you've ever felt before.

Dude, I gave myself a brain aneurysm right before leaving for work, it was intense!

Dave: Did you have an anal aneurysm?
Josh: Probably...

Maneurjism 

This is an over the top ejaculation. One that has been building and feels like you bursted an artery once it happens.
