Phrase: Used when one is too high to fully reply to a 'smoke off' challenge (see smoke off (n)). As their head remains on their shoulder, as they are too high to move, they will mumble 'moke off' so they are not called douche bags for turning down a smoke off.
Consider a typical stoner group of 7-8 people:
Stoner 1: "Pussies, I'm not even high! Smo smo smoke off!"
Said in tandem:
Stoner 2: "Smo smo smoke off"
Stoner 3: "Smo smo smoke off"
Stoner 4: "Smo smo smoke off"
Stoner 5: "Smo smo smoke off"
Stoner 6: "Smo smo smoke off"
Said after stoners 1-6 finish
Stoner 7: "Moke off"
Stoner 1: "Stoner 7 is definitely too high for a smoke off"
