A phrase most commonly used by students, spillage is lickage quite literally means what it says; if you spill something, you have to lick it up. This often refers to a spilled alocholic beverage, but if you also have the misfortune of spilling your meal over the kitchen floor, or spilling your wee sample, you better get licking.
-"Oh my God, I just spilt my drink everywhere"
-"spillage is lickage"
-"I just spilt my drink on her crotch"
