Carpet munching
From Voyeurweb's Wiki about Sex
Carpet munching is a slang expression for lesbian oral sex. Originally derived when few women were shaved and the pubic hair was referred to as "carpet". See more under girl eating pussy.
I guess given the current proclivity for shaving pussy hair, it could also be called 'tile munching'... along these lines, while we are inventing terms, in a male/female couple the female going down on the male could be called 'hardwood floor munching'...?
