Machine Gun Kelly -- Fully Loaded in Hollywood


Rapper Machine Gun Kelly educated TMZ on the fine art of intoxication during a wild night out in Hollywood this week ... but he was so blasted, he probably doesn't  remember any of it.

Do you know what a "Rager Shot" is?? Neither did we ... but apparently, it gets TWO people drunk ... at the same time.

We should let MGK explain ...
