p0oner
A p0oner is someone who has a low score but thinks they're the king of the game. They yell at their teammates like they're the boss, even though they're the one who got destroyed.
"You all are the worst!", after getting killed by a new player." "I give you commands, and you ignore me? What's wrong with you?", while getting killed by a 5-year-old." "I'm the best player here!", after dying 3 times in a row."
