SDIYBT 

An abbreviation of “Start digging in yo butt, twin”, specifically coming from a YouTube video where robot SpongeBob 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: poor imitation of clanker noises SDIYBT
Plankton: what? WHAT!?
Robo-Spongebob: it means poor imitation of clanker noises Start diggin in yo butt, twin
Plankton: oh ok, wait what!? WHAT!?
