seventeenth birthday

The time when a boy/girl turns 17 and grows a tail.

"hey Martha, did you see the tail on that guy?"
"oh yeh, he is hot! Did I tell you I was at his seventeenth birthday?".
"Tail is a euphemism btw".

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

neventies

The neventies is the non-existent decade when something was in style.

Where did you get that coat???

I've had it forever, this was in style back in the seventies.

I think you mean the neventies.
