The loose definition: "It is when you are soooo drunk (wasted) and dudes start dancing with you and you just sort of go along with it and then they start putting their arms around you and you just kind of keep rolling with it because you're drunk and you sort of think the dude is being your dancefloor bro, but then when you sober up you realize that the situash is sort of weird. when this happens, you tell your friends, 'dude, i got so gaysted last night.'"
