Grease Lightning Edit Meaning

1.

Similar to a phantom turd. Where the piece of poop disappears into the U-bend of the toilet and leaves no residue on the toilet paper. But with a Grease Lightning, the only way you know you just pooped was because you ate spicy food and the poop burned your butthole.

It sometimes makes you break into song and dance about the car of the same name from "Grease"

Jake: "I swear I just pooped but it's nowhere to be seen. It burned my butthole from all that spicy food. It must've been the Grease Lightning"

See phantom turd, invisiturd, turd burglar
