Noun: Mainly used to designate a loudmouth punk in any kind of audience. Usually drunk, almost inevitable at comedy clubs. Stand-up comics \ comedians \ and other performers generally hate when they happen --- although they can be viciously eviscerated with fast, ready wit. When a comic shuts a heckler down quickly, the [comics] status goes WAY up, fast. If they flail and fail against them, it can end the set.
Verb: heckle To loudly interrupt a performance with insults, or just [incoherent babbling].
