MGE is the duel training mode from Team Fortress 2 where players practise one on one combat in small arenas. Clips using class voice lines spread quickly through that community because matches start fast and callouts are short. The Engineer go line became a handy shared cue in Russian and English speaking lobbies, edits and soundboards, where a single word could mark the start of a round without any setup. Its short length has kept it in use for gaming videos long after the first uploads.
