P.E.G.S. 

Post Ejaculatory Guilt Syndrome

After a man ejaculates, usually after self pleasure, he feels guilt and/or shame for what he has done. This only lasts for about 15 to 20 seconds.

Male: "Why did I just do that?...I think I just had P.E.G.S.!"

E.G.S. 

1 sub-species of homo sapien who has lost his testicles, having been castrated by a female who now holds said nuts in a mayonaisse jar in the refridgerator.
2 piece of shit, poor excuse of a man with no nuts or friends; who once had said assets.

Look at that poor E.G.S. I wonder if he misses his balls.
