Vulgar term for the female vagina. A cock's best friend and second only to the asshole. A woman's tight snatch is the most precious gift on this earth. Snatch grips and jerks off dicks hence the term "snatch". Snatch by nature's design is to "grab" our meat and "take" our semen for reproduction.
Damn! Amanda snuck into my bed last night and let me fuck her tight snatch!
The second most horrific sounding nickname for the human female's genitals(after cunt). So much so that it can only be properly applied when descibing genitals that are presumed or understood to be filthy or disgusting.
