Fireman Sister

When two women have had sex with the same guy. Akin to the not-so-great male term “Eskimo brother.” So named this because the two women have both “slid down the same pole.” This act brings about a specially bonded type of sisterhood.

Jess: I got way too wasted and somehow hooked up with Brian last night.

Sarah: Ew gross. He’s horrible in bed but now we’re Fireman Sisters since I hooked up with him last year. Cool!
