Rickie Fowler Hollywood Birthday Party, Drinks from Ryder Cup!

Rickie Fowler wasn't just doing shots for his Hollywood birthday party -- he was doing shots FROM THE FREAKIN' RYDER CUP!!

In the ultimate case of "To the victors go the spoils" ... Rickie hit up Catch in West Hollywood with a bunch of his pals, but most importantly -- the 17" tall cup he helped Team USA capture this year.

Of course, when you party with one of the most prized trophies in pro sports, you pick up some celebs throughout the night. Check out the video ... pro skater Ryan Sheckler joined the fun.

And if you're wondering, that's probably not the REAL Ryder Cup. All team members get their own replica, which is still enough to attract Cindy Crawford. #NBD
