1. The word "promo" is short for "promotional".
This word is most known in the Urban scene for being seen on vinyl (LPs, records), tapes and CDs.
Back in the early days of Hip-Hop vinyl production (and still to this day), vinyls were/are given out to DJs known as "promo vinyls". These vinyls are cut (the grroves in vinyls are "cut" using a special type of needle) and given out, usually for free to DJs so that a DJ can play the vinyl in a club or on the radio.
On these vinyls, is the word "promo" written on the record sleeve or record label to tell people that this is a "promo" vinyl that this DJ has. It mostly has "for promotional use only. Not for resale" written on the record case or label instead of just the abbriviated "promo".

BILLY: Not much. Went to Church with my Mom.
SUSIE: Church? But you're a homo.
BILLY: True, but this particular congregation welcomes homosexuals and believes that Jesus wouldn't judge us as wicked.
SUSIE: Oh, so your Church is pro-mo?
BILLY: Yes, it is pro-mo.
CM Punk: Wow, everybody, it's John Cena. He comes out here every Monday night, he's excitable, he throws his hat at somebody, everybody loves it. I am so impressed at how you do that. You get all these people to believe you're that friendly, smiling, everyday man, when I know the truth. And the truth, John Cena, is you're thoughtless, you're heartless, and above all else, you are dishonest. I'm sure there's millions of people worldwide, including yourself, that would love to believe this is over a spilled diet soda, but John, this goes way beyond my spilled diet soda. Yeah. John, you were fired from the WWE. You were gone. You gave a very tear-inducing speech in the middle of the ring about how you finally get to see your mom and hang out with your little brother, and you said you were gonna go away. You were gonna be a man of your way, but what happened? You came back later that night, and then you came back the next week, and then you came back the next week, showing all of these people who aren't intelligent to see through your facade what I have known all along—that your word is absolutely worthless.
