Eskimo brothers

Etymology
Ultimately unknown, but various theories exist. Modern usage was popularized by American television show The League; the term itself likely stems from a misinterpretation or invented hoax about some Inuit and Aleutian peoples' cultural practices of polygamy and polyamory, especially among married women and their male guests.

Noun

 * 1)  Men who have had sexual intercourse with the same woman.
