Concrete dyke

Adj. A concrete dyke is a woman (Undefined, apparently) who's attracted to other women, while having the appearance of an experienced male concrete worker(hence the expression), or a tattoo'ed biker and having the attraction of males similar to a dumpster fire. Usually a social individual, surrounding itself with other of the same species, it will hunt both in herds of smaller numbers. Typical prey consists of Baconators, smaller individual white men, and diet sodas.

Man, if Shaniqua weren't black, she'd be a hella concrete dyke.
