Slug I'd Like to Fuck
Slug as in a woman's damp pussy

Look at that girl over there, what a SILF.
I want you to rub your slug all over my bald head.

Silf

A silf is a "sister i'd like to fuck". it is the same idea as a milf. Silfs are usually absolutely georgous, sexy, irresistable, and extremely flirty

SILF

SILF or SILFing. Self Inflicted Laughing Fit.

A SILF occurs when you do or think about something that amuses you so much you have a laughing fit. You might send a text to a friend that makes you collapse on the floor with laughter.
