Usain Bolt -- FILL UP THE BOOZE BONG!!!!

Usain Bolt is fast ... especially when he's POUNDING ALCOHOL ... and TMZ has the photos to prove it.

The fastest man on the planet went to Jamaica for the holidays to hang out with his parents ... but dude made some time to have a little fun Wednesday at a beach party in Kingston.

We're told Bolt rolled up to the blowout sandbar party in a yacht filled with girls and quickly joined the drunken festivities ... hitting a booze bong and chugging Patron X.O. Cafe ... a coffee-flavored tequila.

Once again, it seems nobody on the planet can keep up with this guy.
