A Brit has slammed the "sweary sign" left by a neighbour on the main door of the block of flats they share - after a dispute broke out over "fag ends".

He shared a snap of the X-rated sign on Reddit prompting others to react with mixed opinions on the matter. "Plenty of younger children in these flats who can read. What a charmer," the man captioned his post in the CasualUK subreddit.
