Grandmaitis can be defined as the symptomatic physical response to going to grandma's and getting fed too much. The bloated stomach, burping, groaning and undoing of pants (not to be confused with Turkey-Coma)
Oh man! I went over and she fed me five meals in one day! :-p Oh man! I have Grandmaitis and can't breathe! If I eat anything else I'm going to barf!
