When you chug a glass of red wine (specifically cabernet).
Waiter 1: I just watched an entire table of girls chug their glasses of wine and laugh about it
Waiter 2: Ahh, the classic fast cab

Get the fast cab mug.
Ordering a bottle or several glasses of Cabernet, generally at a restaurant of repute, and slamming the wine like a Jaegarbomb.
Damn man, that look on that waiters face after the third round of fast cabs was priceless!
