Basically, women who are attracted to women in a sexual way. Lesbians can be broken into two groups, the "good" type of lesbian, and the "bad" type of lesbian. The two groups are defined as follows:
1. The "good" sort of lesbians are the cute ones featured on websites around the world. Well-groomed and
babelicious, these lesbians look fantastic smeared in baby oil, jelly, cream, etc, and don't view men as exploitative bastards who should all be castrated and then choked to death with their severed naughty bits.
2. The "bad" sort of lesbian, i.e. any chick who likes her vice versa and isn't prepared to put on some sort of floor show for the lads. Included in this group are the lesbians who would do a floor show if asked, but are never asked to do so because most guys don't want their eyeballs seared out of their heads by the sight of something resembling Jabba the Hut raping a walrus. Also belonging to this group is your average university feminist who is a lesbian not so much because she is attracted to women, but rather because she's so fucked up that she thinks that all men are just vicious animals who would rape you as soon as look at you. This group tend to have crew cuts and huge Doc Martin boots, and usually belong to some feminist/socialist/fruitcake organisation(s).
Person A: Man, I saw the cutest lesbian chicks on suicidegirls.com last night. They were the goods!
Person B: Better than the ones I saw in the bar last night. Man, I was feeling really intimidated until some Japanese guy harpooned them and dragged them outside.
Lesbian 1: Hey, let's do the decent thing and put on a floor show for those guys over there.
Lesbian 2: But we aren't very attractive...
Lesbian 1: That doesn't matter, I just want the attention.
Watching Guy: Argggghhhh! My eyes! My eyes!
Chick: Men are just sexist, exploitative pigs who have spent recorded history suppressing women.
Guy : I didn't know you were a lesbian.
Chick: That's because you're an insensitive asshole!
Guy : Any chance of a floor show?
