Brown bear clan
Like Eskimo brothers (men having sex with the same female, share an igloo), "cave clan" members have had anal sex with the same female, i. E. been in the same dark hole.
Dude1: That girl ladt night had aunt Flo visiting, do she let me tap the balloon hole.
Dude2: Same with me a few months ago. She was ragging so she let me in through the backdoor. Guess we part of the same brown bear clan now.
