Most likely the group of kids at your school who yell the word 'Gritch' all day and sing dumbass songs with the word 'Gritch' in it. Pronounce 'Gritch' 'gr-EECH' like 'gr' from 'great' and 'EECH' from 'leech'.
another term for a station wagon, mini-van, or any other kind of vehicle that is targeted at the "family" demographic(also M.A.V.)
