An abbreviation of “Start digging in
yo butt, twin”, specifically coming from a

said the phrase (insert some sort of potentially overused “HE SAID IT!” joke here)
Plankton: I command you to make me a Krabby
Patty!
Robo-SpongeBob:

Plankton: what? WHAT!?
Robo-Spongebob: it means poor imitation of clanker noises Start diggin in

Plankton: oh ok, wait what!? WHAT!?
