a sheet of plastic or latex used to protect yourself from S.T.D's during Oral Sex
Yummy, my dental dam still tastes like the fruit roll up that i took it from, sense we all know the the plastic in a fruit roll up wrap is a very good way of using a dental damn!
a mouth piece that covers the lips and creates a hole in the center so that you can give it to dirty hookers and get BJ's without fear of STD's ... like herpes and shit
A dental dam is a piece of latex sheeting (like a condom) that a guy can place over another dude's asshole if he wants to rim him without tasting his shit-hole.
I got so drunk last night that I didn't even know where I was, thank god i saw a used dental Dam on the floor though so i know i don't have mouth Herpies.
A "Denim Dental Dam" is when the genital area isn't clean enough - or doesn't smell clean enough - to perform oral sex on the other party without a barrier to protect ones mouth. It is therefore necessary to have the denim jeans remain on the party to which it will be performed.
