Post Malone Might Be Launching Beer Pong League, 'World Pong League'

Post Malone is taking steps to turn his favorite drinking game into big biz ... we've learned the wheels are in motion for a world beer pong league!!!

The "Beerbongs & Bentleys" rapper is looking to lock up the rights to "World Pong League" ... and Post and his legal team have gone so far as to file for a trademark on that name.

According to the docs, obtained by TMZ, Post wants his "World Pong League" to operate official beer pong tournaments, competitions, events and exhibitions.

And, just like the NFL, MLB or NBA ... ya gotta have merch! Post plans to put the league moniker on beverage glassware, drinking glasses, plastic cups, game tables, cup racks, balls and every piece of casual sportswear -- including boxer shorts -- under the sun.

Basically, everything you could possibly associate with sport of (drinking) kings and queens.

As you know ... Post is a huge beer pong fanatic, and he loves to raise the stakes. PM won $50,000 playing pong with Tyla Yaweh.

We're told the "World Pong League" is the brainchild of Post and his manager, Dre London, but the idea is only in its infant stages -- meaning, all you amateurs still have time to practice.

Aim well and drink wisely, friends.
