The act of being a complete and total fool, jackass, or moron. Doing acts that are not considered proper in public, or even in private. Only the dumbest of people can achieve the level of hardcore derping. A prime example would be when Simon Cowell completely degrades a great singer, that is hardcore derping.
Bob walks in. "Man you were Hardcore Derping it at the party tonight". John throws beer can at Bob. "Derp."

Get the Herp derpmug. 
Violently thrashing your torso resulting in your arms flinging about and slapping unweary passersby. You must let the movement of your torso fling out your arm, it is not a derp slap if you move your arm yourself.

Get the Derp slapmug. (noun) a fictitious gland responsible for the filtration of derp-worthy stimuli in the human brain.
in a healthy and intelligent individual, it acts as a sensor, indicating when something outrageously stupid has been processed. it tends to result in facepalming, headaches, or sympathetic lulz in defense of knowing that the demise of mankind is imminent.
in an unhealthy or stupid individual, it provides a positive-feedback mechanism, resulting in the individual gaining reward for filling their brain with even more useless bullshit. stimulation of the gland in this type of individual brings about erratic, borderline retarded behavior, and in fact causes them to emanate even more derp to the surrounding environment. this can lead to a derp cascade, which enthralls masses of stupid individuals to do stupid things.
