'Pineapple on the grill' is what you yell when you see a hot chick walk in your restaurant (i.e. The Keg). The cooks usually yell this when they spot the hot chicks from the broiler bar, then they proceed to take turns fingering the prime rib.
Sweaty cook #1: "Hey dude, check out the talent that just walked in!"

Sweaty cook #2: (yelling at the top of his lungs) "PINEAPPLE ON THE GRILL!!!"

All male restaurant staff the proceed to the hostess station to check out the sweet ass.
