Buttering both sides of the bread

To go much harder than is necessary. Worthless overachievment.

"Aww man, I studied for three hours and the test turned out to be easy! I really buttered both sides of the bread on this one."

"Dude last night I took ten viagra before fucking my girlfriend!"
"Woah man, why you always gotta be buttering both sides of the bread?"
