big boy drink 

Generally speaking, a big boy drink is an alcoholic beverage that is served in a rather large cup (like, say a big gulp cup) and is usually mixed with hard alcohol and a soft drink.

Bryan wanted to fix himself a big boy drink before last night's Halo session, but, unfortunately, he was out of Mountain Dew.
