Get the Dummkopf Know-it-allmug. A stereotypical social media commentator, usually with a beard, who likes to hear themselves speak as if they are an expert on a given subject, but their expertise might be questionable.
The bearded know-it-all gave me an unsolicited lesson on what he thought was the proper way to drink bourbon.
The bearded know-it-all mentioned on his podcast that birds are direct descendants of dinosaurs.
The bearded know-it-all argued that there is no difference between micro and macroeconomics.

Get the Bearded Know-It-Allmug. A name given to a person that expresses basic common knowledge about a subject, by a person that doesn't know shit about fuck on said subject.
Me: Hey Edgar, maybe you should just check to see if the outlet is blown before you start taking apart the DJ's mixing board.
Edgar: Oh dang man, that actually worked! Quit being such a know-it-all, you're making me look bad.
