Noun: a sexual act: a sort of hybrid of the Change Machine and the Birmingham Bootycall. Specifically, when a roll of quarters is placed in a woman's vagina, and a phone set to vibrate is placed in her anus. The phone is called and the vibrations cause the quaters to fall out. It has nothing to do with Pensacola.
Woman: Jill, kill me now. Last night I got really drunk and let Randy do a Pensacola Payphone on me. Now my phone's ruined and I'm out of laundry money.
