Thank you to Shiary for the idea.
Kili didn't like washing clothes. He was fine with most chores except for washing. To Kili, it was the ultimate degradation of a male. It was the lowest a man could sink when he had no woman around to do the washing. (This was a feeling he never told his mother, understandably.) The morning he was due to do the washing, Kili set up for what he considered his finest prank yet. Thorin was starting to watch Kili closely. (When Kili told Fili that he couldn't imagine why, his brother rolled his eyes.) So, Kili was set to washing the clothes with Dwalin standing guard. Kili made sure to act completely submissive. He kept looking side ways at the older dwarf as if blamin him for not being able to pull a prank. (Kili thought that was a stroke of genius.) It wasn't until he saw the dwarves faces when they saw clothing that he had washed and that they had to wear that the thought that maybe, jusst maybe, he had gone a little, really only a tad, too far this time crossed his mind. (He did think that Thorin did look very pretty with those grey eyes and black hair of his, though. (He only shared this thought with Fili though.)) Thorin did not agree, and the next rule was made.
If Thorin's clothes ever become pink again, he will dye Kili's hair and stubble permanently pink.
Review with a comment and suggestion for the pranks, please.
