a term used to explain something that is so utterly disgusting you just can't find a gross enough word to express how you feel. It is a word that is combined from Gross and Grolsch (the beer) because to be honest Grolsch is a really gross sounding name for a beer, or actually... ANY type of liquid substance. ew.
pronounce it as best as you fucking can.
