Team Boo

Team Boo is a term primarily used within online communities, particularly those centered around video games, competitive events, or online personalities. It refers to a group of individuals who publicly and enthusiastically support a particular contestant, player, or team while simultaneously expressing opposition to or dislike for their opponent or rival. The "Boo" element signifies active and vocal disapproval of the opposing party.

The practice of forming "Team Boo" is often lighthearted and intended as a form of humorous rivalry or playful banter. However, it can also escalate into more aggressive or toxic behavior, particularly when directed at individuals rather than teams or organizations.

The phenomenon is most prevalent where there are clearly defined rivalries or matchups, and where strong opinions and emotional investment are common. The formation of a "Team Boo" represents a public declaration of allegiance and a willingness to participate in the often-spirited discourse surrounding the event or competition.

The term can also be used more generally to describe any group of people who are united by their shared dislike for a particular entity, even outside of competitive contexts.
