The Game is So, So Thirsty For Vodka

Game got a thirst-quenching assist onstage from Diddy ... Ciroc, and lots of it.

Game went on at midnight at The Venue in Minneapolis and a half hour in, his crew busted out the vodka. Sipping turned to chugging and you know the rest.

The vodka didn't get in the way of the concert ... which went beyond 1 AM.

Effen awesome!
