Extremely intoxicated to the point of no return.
Your
gullet is a funny word to describe your mouth, throat, and stomach region, hence an individual who is off their
gullet may be projectile vomiting as a result of being so intoxicated
Frat guy: “Dude you gotta get up, your ride is here!”
Dude who is fighting for his life on the toilet: “I
literally can’t guy, I’m off my
gullet.”
His ride: “How much have you
drank dude? You are off your gullet!”
