sweet seventeen 

A birthday where a girl turns seventeen, often used to make up for a failed sweet sixteen.

Person 1: Amy's having her sweet seventeen on Friday.
Person 2: isn't that meant to be sweet sixteen?
Person 1: poor thing, her parents caught her giving head before her sixteenth birthday and got so pissed they wouldn't let her throw a party
