an irrational, idiotic manbaby. The name derives from the latin word Gruuknalia (meaning uncontrollable rage). A grunk is a person who is incapable of basic human speech and communicates only via grunts, shrugs and inchorent crying. Many teachers at a school will try to take care of a grunk and try to contain him. But from the Non-stop screaming and shaking to the constant barrage of fully used diapers, grunk(s) will usually be distributed and sent to the SCP foundation to be contained securely.
