Jumpin Biddy

root@bandit-db:~$ cat description.txt

A Bandit Bouncing Betty that keeps hopping while spraying bullets around itself for a short time. Individual hits are weak, but the repeated bursts can stack up quickly as it drifts toward nearby enemies, making it useful for area denial and for flushing targets out from behind low cover. It also creates a small blast when it starts and when it ends, and the bullet spray does not hurt allies.

Some versions appear under the alternate name "Jumpin Bitty." Both names reference the Bouncing Betty mine.
