Mogstash 

The longer hairs that protrude either side of a woman's underwear or bikini.

A fishy smelling mustache, also can be protruding from the undies.

Dude, I was swimming in the pool yesterday and when i dived underwater I saw this this fat chick had a proper Mogstash hanging out. It looked like a walrus down there.

crotch moustashe 

see also: crotch whiskers. This term refers to folds of fabric in the crotch-groin area, most frequently happens when pants are too tight, but can also occur when pants become wrinkled from sitting too long or if the pants fit poorly. The fabric folds of the pants in the crotch-groin area create the illusion that crotch has a moustashe, or whiskers.

Dude #1: I couldn't concentrate on what she was saying, I was too distracted by the crotch moustashe...
Dude #2: It was more like whiskers!

moustasha 

(Popular in Algeria) Women who aren't good looking and also deeply materialistic

Kadour (not very rich, but a good guy) : asked Imane out , she bluntly refuses (you don't own a nice car)

Saiid (rich, bad guy and probably old as well) : stop beside Imane with his nice car, she goes in (without a second thought)

Kadour: she's such a Moustasha
