Someone who is a complete know-it-all on a particular topic is referred to as a badger. This is usually used as a insult and a basic indicator to remind them to shut the fuck up.

Baden is probably some German dude, he has a HUGE dick, bigger then big. He is also a king and loving person but can be a playa so guys watch out he's gonna steal your girl.
Girl 1: Is that Baden over there?
Girl 2: Yeah, apparently he has a huge dick!
Girl 3: Oh yeah, Megan told me that apparently its the biggest she has seen!
