Is there a pejorative term or phrase that lesbians use to refer to straight women? There seems to be a wealth of terms (both offensive and inoffensive) that are used in the other direction. I ask because two lesbian employers of my wife were expressing disgust at some of her sexual practices (don't worry, I am not going to go into detail). If there exists such visceral disgust, it seems as if words or phrases would have been coined to express it. I will not ask the two principals of this discussion since that would require bringing back up an uncomfortable conversation that should have probably never happened in a "professional" environment.
I can't think of a term that lesbians exclusively use to describe straight women, but there are terms used to describe acts that, obviously, only heterosexual women (and gay men) will do. It isn't hard to imagine lesbians using these to spite straight women.
There's the sexual slur "sword swallower" (originally Australian, 1800s), as well as the extremely vulgar term "cocksucker"--a woman (or a man for that matter) who performs oral sex on men (obviously, lesbians won't do this).
There are terms such as "one-way" (used in the gay community in the 1960s, US) , "het" and "breeder"-- all three are terms referring to "a straight person".
