Two men who have both had sex with the same woman at some point.

A pick me is a woman that is willing to do anything for male approval. She will embarrass or throw other women under the bus to achieve this goal. The unfortunate thing about a pick me is usually the men they are trying to seek approval from are of poor quality and treat women badly, leaving little real benefit for the pick me.

Two guys that have had sex with the same girl.

When 2 guys have sex with the same woman that makes them "Wiener Cousins" which is an unbreakable bond that men must obide by!!

Two men who have shared the same girl in bed.

Two or more men who have had sex with different women who have shared at least one partner. A simplified explanation is that a wiener cousin is the wiener brother (wiener buddy) of your wiener brother but is not your own wiener brother. Additionally, the wiener brother of your wiener cousin is also considered your wiener cousin. Though in this instance the designation of proximity is necessary; 2nd, 3rd, 4th, etc.

Two gentlemen become Wiener Cousins when both are Wiener Brothers with the same third gentleman.
To further explain, if Jeeves and Jay have had both made love to the same woman, thus becoming Wiener Brothers, and Jay and Aaron have both made love to a second woman, creating a second Wiener Brothers relationship, then Aaron & Jeeves are Wiener Cousins through their shared relationship with Jay.
