An acronym for 'Passed the Fuck Out' or 'Pass the Fuck Out'.
It is applicable when one is not so much asleep as passed the fuck out. PTFO can apply to anyone who is
drunk, high, or simply tired as fuck. PTFO happens in random as shit places, such as the
school bus, Starbucks, floors, creeks, and isolated mattresses.
A PTFO can easily be identified by how
funny the person looks while they are PTFO.
