derp
A simple, undefined reply when an ignorant comment or action is made. Brought to life in the South Park series, when Mr. Derp made a guest apperance at South Park Elementary as the chef for a day, followed by hitting himself in the head with a hammer and exclaiming "Derp!"
derp
Word uttered by morons after they do something incredibly dumb, which will be often seeing as how they're morons.
Watch me hit myself with this running chainsaw.(Cuts his arm off). Owie, that hurt! DERP!
derp
A derp is the guy in the bright clubby striped shirt who waits in line for 2 hours to get into, well, a club. Granted, it’s nighttime, but the derp still wears the euro-trash sunglasses. The derp has far too much pomade in his hair. On top of this, the derp acts like he is a member of high-society, when in fact the derp is actually just high-maintenance white trash.
