Joe Buff

Joe Buff, a term popularized within online gaming and internet culture, refers to an individual who possesses an overabundance of knowledge or skill in a particular subject, often characterized by an eagerness to demonstrate and expound upon this knowledge. The term often carries a mildly pejorative connotation, implying the individual may be unaware of their own verbosity or the disinterest of others in their detailed explanations.

The term is often used lightheartedly, but can also suggest a lack of social awareness or sensitivity to the conversational context. A "Joe Buff" is generally understood to be well-intentioned but potentially tiresome due to their exhaustive and often unsolicited expertise. The scope of expertise can vary widely, ranging from obscure trivia to complex technical details. The term is frequently applied to individuals who are perceived as being overly enthusiastic and thorough in their explanations, even when a simpler explanation would suffice.
