Sister Lesbians

Two women who are either lesbians, or sisters, or both. It is often times difficult to determine which.

Lesbianister

Where one lesbian is determined to turn a straight person gay, this is in an obvious way that the other person is clearly aware of.
It is often used among joking conversation as an insult between females.

Oh my god your such a lesbianister, please stop it.
