As One Pleases
One's Own Convenience, One's Own Way, One's Way
noun, な adjective
The hand (or person, as you know 手 often refers to a person) that wins gets to do as one pleases without regard for anyone else.
The reading for this is weird. It's all kun'yomi, which luckily you've seen before, but still strange. I guess when you do as one pleases you can read kanji however you want, in this case the kun'yomi readings. Do note that there's a small っ in there before 手, presumably to connect the two readings of the two kanji together.
You are so selfish!
Don't say whatever you want.
"Salmon! Fugu cheated on you five times. Never trust a guy like that." "I know… but he says he can’t live without me." "Well, suit yourself then!"
