multitasking
A nice way to say that you're doing many different things at the same time. And since no one can divide by 0, that means you're doing many different things half-assed.
Example:
Joe thought that he would multitask by doing his physics homework during his math class. His multitasking, however, got him a detention and a failed homework grade instead.
