Define Grubbs Sandwich Meaning

Grubbs Sandwich
A delicious sexual sandwich involving an obese blonde girl as the meat of the sandwich and one of the slices of bread should be a pasty hispanic fat girl overachiever while the other slice should be an attractive buxom chick so that theres some hope for enjoying the sandwich, but really theres none since its a Grubbs sandwich and cant be enjoyable at all.

"Dayyyum I thought the Grubbs Sandwich was gonnna be at least a little enjoyable with that big boobed chick in it but the fat chicks kept ridin on me and the meat girl squashed me! Mah dick aint been straight since."
