The release of such an ungodly fart that its potency and duration make those around the farter believe that the farter did not merely fart, but indeed shit his pants. Usually either an insult at the farter's discourtesy in not leaving the room, or a proud boast to indicate the true power of methane.
Me: <Sniff, sniff>...what the fuck, who shit themselves?
Used in the film "Flight of the Intruder" in the court-martial scene. To not necessarily use religion and tell the truth. Repentance, but without religious overtone.
from "Flight of the Imtruder":
"I hope you realize that now is the time to come to Jesus." Meaning that if the aircrew being court-martialed spilled their guts off the record before the proceeding started, they might stand a better chance of a favorable opinion. Could somewhat be compared to plea bargaining.
