Keeper Zach Hemming branded Somerset Park a "s***hole" following Kilmarnock's win over rivals Ayr United.
Tommy Wright 's side climbed to the Championship summit with a 1-0 Ayrshire derby win at the home of their old foes on Tuesday.
Oli Shaw's late penalty claimed three points for Kilmarnock in front of a 6,000-strong crowd.
Hemming, on loan from Middlesbrough, took to social media in the aftermath to savour victory in a rare league meeting between the sides.
He only arrived in Scotland in June but it hasn't taken long to form an opinion on a particular corner of Ayrshire.
Accompanied by a photo of himself in action, Hemming wrote: "Derby win under the lights, another clean sheet and top of the league, what a night."
But more eye-catching was where he'd marked his location above the snap.
It simply read: "S***hole"
That's certainly one way to wind up opposition fans.
