A term used to describe when a friend comes over to your party, plops himself at your serving table, and proceeds to eat directly off the serving platters. This typically occurs at a baby shower where said friend omits to bring a gift other than his ginormous gut (aka- SCSG "Santa Clause Sized Gut").
Bagels: Haha, did you hear Chi Chi did not bring Pillz a shower gift?
Jr: Good lord.
Bagels: OMG check it out! Chi Chi is over there BIBBED UP at the friggen kitchen island where they are serving all the food. What a disgrace.
