This is an abbreviation of ones fetish with chubby girls and punk girls. There is no such thing as CPG porn but it wouldn't hurt to try looking at pictures on your cellular phone then giving it to your friend and them putting it all over the internet.
Chubby Punk Girls (CPG) Getting Fucked In The Ass
The hottest, wildest, drunkest, most fun girl you've ever met.
CPG originated on the mainline around 2008 thanks to the Academy of Notre Dame's own HEM. She marketed this word through the thick green bracelets that the "cool" girls weren't caught DEAD without. CPG didn't only stand for CrazyPartyGirl but it stood as an iconic symbol of mainline prep/money/fun/style. CPG began to be a word thrown around as a pseudonym for popular kids who partied on the weekend (or in Avalon in the summers). Let's just say, if you weren't a CPG you were dying to be one.
However it later was used to speak ironically about ones idiotic friends and their drunk faux pas.
CPG was an everyday word, thus tapering off into the abyss of useless acronyms
Girl 1: Holy shit, they get drunk every weekend in that Prep guys basement when his parents are home.
Girl 2: I know I hear they all make out in the home theater.
Girl1: True CPGs
(Friend pukes into a McDonalds bag while walking through Wayne PA)
Girl 1: (says to puking friend) haha stop being a CPG!
I heard you have been selected into the commission, hell yeah-CGP!
i would difine C.P.G (tell you what it stands for) but we're way to cool for that so suck on a chode.
