Derp
Derp is a purely cosmetic Fun module that constantly changes the head rotation other players see, so your character appears to look around wildly, stare straight down, or spin in place — all while you keep playing normally. It only affects how your head is presented to the server and nearby players; it does not change where you are actually aiming on your own screen.
Use the Yaw selector to control horizontal head movement and the Pitch selector for vertical (up/down) movement. By default both are set to Random, giving a chaotic, twitchy look. Other modes let you lock to a fixed angle, add an offset to your real view, jitter back and forth, or continuously spin.
Keep SafePitch enabled to avoid impossible up/down angles that look obviously fake, and leave NotDuringSprint on so the derping pauses while you sprint (handy if you don't want it interfering during movement). For more silly cosmetic effects, pair it with SkinDerp, HandDerp, or Twerk.
