y-fronts 

Typical guys' underwear. There's and opening at the open end of the 'y'.

Last Halloween Roscoe stuck some dingy y-fronts on top of his head and ran down the street shouting,"Pwip!"

Y.A.S.A.P 

If you want to tell a friend to watch a video or listen to a song via 'youtube', then instead of asking them to do it A.S.A.P or go-and-watch-that-video-now, you simply say Y.A.S.A.P (youtube that A.S.A.P).

John: Have you heard that Kendrick Lamar song 'Ignorance is bliss'?

Sam: Ahh, nah man I aint even heard it yet

John: Y.A.S.A.P

y-fronts 

old-fashioned underpants so called because the fly is made up of an upside down Y shape allowing quick access but still affording cover

Chris "Y-fronts" B***** MP was so excited by Tony's first election victory that he lowered his trousers in public and started masturbating, while singing Things Can Only Get Better and inviting men to perform oral sex on him.
Call me old-fashioned, but what's wrong with a glass of champagne

Y'know ahmen 

A phrase uttered by select persons every ten seconds. Akin to "ummm" which is used by many people. AKA, a filler phrase.

"Y'know ahmen, that's not what I'm talking about."

"You have to do it this way, y'know ahmen?"
