A flood wall often made of rock and earth. It is chiefly British, spelled Dike. It may also be a ditch or channel. In Geology, it is a long mass of igneous rock that cuts across the structure of adjacent rock. The use of a dyke may cause severe flooding on the other side of the river and up-stream of the dyke.

This is also the original meaning of the word, in comparison to the new, generally accepted meaning referring to lesbians.
Because of the dyke across town, the flood was significantly less devistating.

Though it's a risk, there is a small hole in the dyke to let water seep out through more quickly.

a bitch who likes bitches.
will often pass herself off as bi or straight, but 90 percent of the time the bi ones will "come out to you" after about 4 months, and basically throw your feelings back in your face. two days later youll see her with some other dyke, making the wound deeper.
girl:i really, really love you.
guy:ok, i love you too.
girl a month later:i like girls now
guy: fucking dyke

A female who could kick your ass, fuck your woman, and make you eat dirt.

This is a very dangerous person. She is not to be fucked with. Unless you want to see your wife being banged around by a girl and loving it!

A dyke usually obtains some type of employment usually reserved for males such as police officer,truck driver,etc.
A dyke took my wife and left town with her.
