One of my favorite Twitter accounts to follow for golf is @NoLayingUp.
They refer to themselves as "golf fanalysts" and they're always posting funny stuff and inventing hashtags such as, "#TourSauce" (basically the art of anything dramatic in the game -- club twirls, holding a pose, tossing a club, etc.), and "#PrayForTedScott" in reference to the caddie for Bubba Watson, who has been on the receiving end of many an outburst by the two-time Masters champ.
Along with all the funny stuff, @NoLayingUp also puts out some really cool stuff -- like this infrared Vine of a Rory McIlroy swing with a driver that was posted today. Check it out:
