Bat dropping (sometimes abbreviated as BD) is a technique used primarily in the Home-Run Contest minigame to rack up very high damage on Sandbag. It is the act of dropping the bat over Sandbag, then hitting the bag with a move that does not send Sandbag flying, usually a meteor smash to hit the bag back into the ground, or some weak attack that negates the knockback of the bat drop.
Captain Falcon or Ganondorf's bat dropping technique is a classic example: they jump over the Sandbag, drops the bat, and then hits it with down aerial. The bat knocks the bag in midair and the spike immediately hits Sandbag back down; thus, Sandbag doesn't move. The bat should have bounced off Sandbag, so Falcon can jump and catch it again with Z, after landing. With L-canceling and fastfalling, one can achieve very high scores.
Not all characters have to use down aerial; examples are Mario's forward aerial, Yoshi's forward aerial, and Falco's up aerial. The timing for every character is different, because of varying falling speed, attack speed and jumping height.
- Spacing: Spacing is a simple concept; it just means changing the position of one's character to improve a strategy.
- JJC: Jump Jump Catch
- JCJ: Jump Catch Jump
- Singles: Single jump bat drops
- Delayed fastfall: Generally applied in high-level strategies, the delayed fastfall involves dropping the bat, starting the move, then fastfalling. Most often used in single-jump bat drop strategies.
- DBD: Double Bat Drop: Brawl Only. This involves dropping the bat, catching it again, then dropping it again. Can be followed with an aerial, or a simple jab.
- TBD: Triple Bat Drop: Brawl Only. Same as Double Bat Drops, but this time, dropping the bat three times. Impossible to follow with an aerial, but jabs are possible. Usually used with a pause in between the second and third bat drop.
