faceplamm
A faceplamm is when someone’s face gets smashed by their own hand because they’re too dumb to realize they just made the worst mistake ever.
My math test says 2 + 2 = 5. I faceplammed so hard I broke my pencil.
I told my boss I was sick. Then I got a call from my boss. I faceplamm-ed.
My dog ate my homework. I faceplammed and cried on the floor.
