Mangina

The practice of neatly tucking your penis (and if you can , your testicles) back between your legs obscuring them from view to either achieve a comical or deeply perverse effect depending on your motive.

Comical:
"Wehaaay! Look at this lads! Check out my Mangina! I'm your Mum!"

Perverse:
"I'm trying to groom my girlfriend into being a lesbian. Tonight I will give myself a Mangina and see if she will go down on me."
