What are Eskimo Brothers?

Eskimo Brother:

When two males acknowledge having been intimate with the same female and remain on good terms, the men are now bonded by having shared the same igloo at one time or another.

This can lead to perks by making the information known to other males who you can network with.

Male 1: “Yea man, I got us a hook up at the show tonight, we don’t have to pay cover”

Male 2: “Sweet, how’d you score that?”

Male 1: “Me and the door guy are eskimo brothers, remember that blonde girl from last weekend?”

Male 2: ” props!”

OR

n. A male who has had sex with, and ejaculated inside of the same woman as a good friend. (not necessarily simultaneously)
I knew me and Jack were brothers for life, but when I found out he slept with Stacy we became Eskimo Brothers

This is from “the League” and from urban dictionary.
