HAMsgiving
The weekend directly before Thanksgiving in which you and your friends spend time going "Hard as A Motherfucker". This is done in preparation for actual Thanksgiving where going HAM is not appropriate in front of Grandma.
Richard, why are you drunk and yelling profanities at the television? Didn't you get enough of that last Sunday during HAMsgiving ? Next year maybe you should stay in Vegas for a couple more days.
