D-Dogg Kidd
A loudmouth who crashes every chatroom like it’s a party, steals the spotlight, and disappears before anyone can say anything.
D-Dogg Kidd joined a study group chat and said, "I’m here to chill and flex." (He left after 2 minutes.)
He joined a gaming chat, said, "I'm the best player here," and quit before anyone challenged him.
He showed up in a math chat and said, "I solve problems faster than you." (Then he vanished.)
