gorgethon

to stuff your face consistently; to eat like a pig over a long period of time; to indulge in gluttonous eating to the point of feeling like you are going to puke usually during a holiday meal such as Thanksgiving.

Leanne: Man, did you see Mike at Thanksgiving dinner? He devoured that whole 35lb turkey himself and left us only scraps.

Liz: Yeah, he musta been on a gorgethon. What a pig!
