Chaos muppet
(1) A person of frantic and/or ridiculously silly demeanor, and so is hard to take seriously muppet and who moves, uncontrollably, from one overwhelming, confusing, or dangerous situation to the next as a way of life. (2) a muppet addicted to chaotic situations, people, or experiences. In all, chaos muppets get in over their heads but know of no other way to seek out new people or experiences; hence, like muppets, they lack control, focus, and/or self-awareness/ regard. Like an adrenaline junky, but sillier. (3) Someone who is, as a rule, always in over his/ her head, usually thinking he/ she is in total control...
Last week, he downed a bottle of sriracha, went skydiving, and then smoked crack all night. Mark is such a chaos muppet!
