y/n 

Saying y/n parodies the old DOS programs people used back in the day. It means yes/no, and some geeks still use it when they ask questions.
For example:

"you want me send you that file y/n?"
"you wanna come out y/n?"
"y halo thar buttsecks y/n?"

Y.B.F. 

Y.B.F. -- "Yellow Beaver Fever" is the condition of Western men who are compelled to chase any girl who is Asian. More commonly referred to as Asian Fever and an asian fetish.

Rob Pongi has such a bad case of Y.B.F. he has trouble keeping his trousers zipped up whenever he leaves his apartment and goes into the seriously babe-infested Tokyo environment.
