Aka jumping the gun. When someone is prairie dogging for a long time and can not hold it any longer. They run to the tiolet and don't have enough time to think. They sit down, shit, but do not realize they didn't lift the lid. Therefore making a mess all over the lid, bowl, and/or walls.
Jermaine: Did you hear bout Dwayne?
Jamal: Ya i heard, he was so pissed drunk he shit the lid.
Labron: Damn bro that gross, now i gots to clean that shit up.
