RORY McILROY took six shots to get out of it - and the Coffin bunker at Royal Troon's Postage Stamp hasn't finished messing with the world's best yet.
Now the cardwrecker beside the 8th green has its own Twitter account, and it's already been blocked by two top professionals!
The profile@TroonCoffinTrapclaims American Ryder Cup star Patrick Reed and former FedEx Cup champion Billy Horschel have banned it from their accounts.
After McIlroy's debacle in his practice round, the profile posted a message asking the four-time Major winner if they were "still cool".
But away from the obvious danger the five bunkers around Troon's short signature hole represent, the "bunker" offered some support to the pros who showed it respect.
Andrew 'Beef' Johnston - who told SunSport about how he ended up beside a pool in his boxers after a drinking session with John Daly - called the par-three "wicked".
But the 300-1 outside shot was invited back there to celebrate with the Claret Jug should be strike gold in his second Open appearance.
Beef's fellow countryman Ross Fisher wasn't treated so favourably though.
He posted a photo of his locker for the week with the message: "Feels real when you see this."
But the "bunker" replied it would "feel even more real" when he struggles to hit a shot out of the trap.
But probably the most menacing message came in reply to a video posted by Bubba Watson's caddy that showed American star JB Holmes escaping from one of the bunkers.
The account wrote in reply: "Try me in competition. Your balls are all mine!"
