Get the Back Alley Sally mug.
To leave some sort of engagement (a party, bar, wedding reception, etc.) without saying goodbye or having anyone notice until well after you are gone. Usually done if the individual is too drunk or tired to go on, but doesn't want anybody to know.
1- "Hey! Anyone seen Buddy?"
2- "No, not for an hour or so... must've pulled a back alley Sally!"
