fag wagon

A wagon or car full of Fags(Homosexuals). Used as an insult, it dates back to when bundles of sticks were transported by horse-driven wagon. It is used most commonly when someone and or a group you didn't invite to your party shows up anyway.

Jaime: "Shut up! do you always have to be such a douche!? GAWD!"
Bruce: "YAYE!!!"
