Bad manners

In multiplayer games, to show bad manners or BM is to disrespect the opponent.

Common BM methods include:


 * Spamming the hard drop key;
 * Soft dropping every piece;
 * Using impractical openers such as the Sus Opener;
 * Taunting the opponent in chat.

As the term implies, it is generally considered rude to BM, especially in ranked or tournament matches where serious play is expected.
