P.O.B syndrome 

Pain Of Balls syndrome
The pain in your testicals after having a mega boner for roughly 3 hours in your pants, due to the fact that the girl doesn't want to have sex or even touch your junk

I had P.O.B syndrome last night, my girl friend wouldn't even touch my dick, i couldn't walk for 3 hours it hurt so much.

B.Y.O.B 

B.Y.O.B is an abbreviation of bring your own booze. Usually used by the hosts of house parties, telling their guests that alcohol will not be provided.

At Janine's house party last week, she texted everyone saying 'be here for 7pm and B.Y.O.B'
