Pro-drinks 

Pro-drinks are similar to pre-drinks, except you and/or your friends consume excessively more drinks than a normal pre-drinks session. May even lead to failure to go out afterwards.

Ryan was refused entry to the club because he was too drunk from pro-drinks!

Our pre-drinks turned into pro-drinks when Steve had 15 jager bombs.

#1. I remember when Karl had his first beer; he could barely hold down a Miller Lite. Now he pounds Heineken like it's water. He's ready to step up to the pros and have a Guiness with Rick.

#2. Danko, the quentessential semi pro beer drinker, had two beers, then his pants fell down and everyone saw his Blue Moon.

#3. CR had a partial rod from staring at all the prime booty while he slammed a few Modelos.

Predrinks 

Sometimes shortened to pre. A small party usually held in someone's house where people drink store bought alcohol before going out to a bar or club. This usually means they are tipsy or nearly drunk by the time they arrive, meaning they do not have to buy expensive drinks at the bar

Joe - "Are you going out tonight?"
Jason - "Yeah, Emma's parents are out of town so she's having predrinks at hers"
Joe - "Count me in"
