Its when you are having anal sex with a condom on and then the condom falls off and gets lost up there and you have to try to find it and when you pull it out its all bunched up and white like a goat.
Me: hey see that chick over there? Friend: yeah. Me: I fucked her Friend:why don't you ho talk to her then. Me:Because the night was ruined by a lost goat.
