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.

Dyke also known as "Robo Lesbians" is a term often used in the Midlands area of England, a play on the original meaning of Dyke meaning "Lesbian" in that Dykes are often girls that act as heterosexuals but seem to pride themselves on wearing all of the same style or brand of clothes and using all of the same dyke-like lingo. Dyke groups normally form when a group of girls have recently all broken up with their boyfriends, who they all collectively hate for totally inane and irrellevant reasons.

Dykes often appear to be flatchested (rarely having a cup size larger then C), they stick together in groups, often to comment on what people are wearing (or what they should be wearing). They often dress in the same clothes and believe men are the inferior gender, unless they are really handsome/buff (or easy). They listen to the worst of chart Music (Lady Gaga, La Roux, Florence and the Machine) and they are one of few reasons why the hideous industry of Music is making any money at all.

Slaves to pop-culture, they have to indivudality whatsoever, and will change their personalities to fit the stereotypes of pop-culture at the time.

To emphasise completely normal points they use words like "actually" and "can you (actually) not?".
"Dyke 1: I'm really thirsty"
"Dyke 2: Yeah, me too, so thirsty"
"Dyke 3: I'd really love a drink too"
"Dyke 4: Wanna go get a drink?"
"Dyke 5: Lets actually get a drink"
"Dyke 6: Yeah, I'm parched, lets 'roll'"

a REAL butch lesbian; one with a crew cut hairstyle who wears taper legged Lees, Wolverine workboots and flannel who shouts out things like "hey brenda! gimme a lift my truck's broke again!" in a husky HUSKYASS voice.
k.d. lang. remember, all dykes are lesbians, but not all lesbians are dykes.

A woman who's sexually attracted to other women. (Not to be confused with bisexual) A dyke is only into women! A lesbian only likes girls too, but can act and appear straight. Where as the "dyke" is pretty obvious. A dyke is more manly and masculine.
Somebody throw that dyke a ruffle! Hell put some make up on her too while you're at it.

Lets face it, i know a lot of people will agree. A dyke (Not dike) is referred to a lesbian, sometimes referred to someone who likes the opposite sex. Mostly means lesbian. I have herd some people call gay people dykes too, thats why i put it in the definition...so theres proof.

Simple as that.
The woman/man is a dyke.
