Get the Sugar Stain mug.
A white/light stain left on a man's trousers/pants, usually on the crotch area. This stain may be from sperm, cum that is left on there, but may also be a coincidental white stain, from milk, PVA glue, etc.

Sugar stains can also be found on other pieces of clothing or surfaces. If you see a sugar stain on some one, make sure that you bring it to their attention that they have one.
Hey Lev, you got a sugar stain!

Is that a sugar stain, or did you spill glue over your crotch again?!

Dude how did that sugar stain get up THERE?!
