Flashbang wank 

A flashbang wank is when an individual decides to masturbate or engage in sexual intercourse whilst tackling a throbbing headache before the event. The word ‘flashbang’ comes from the sheer brain fuckery that is experienced after ejaculation. The pain is so awful that you don’t even have time to clean up the bodily fluids due to having a strong urge to hold your head against a pillow to calm the pain.

I had a flashbang wank earlier babe, and it was the most unsatisfactory wank i have ever fucking had. However, it wont stop me from flashbang fucking the shit out of you later.
