A game in which someone grabs your hand really tight and swings your arm back, giving you lots of pain. When it starts to hurt like hell you shout "Mercy!" really loud. The point of the game is to see who can go the longest without saying mercy.

Known as "nobility's true badge" (William Shakespeare). Mercy is helping a person, even if you come off as a bitch. It means being compassionate and sometimes forgiving. Or when you feel so fucking bad you decide they'll let that person continue their lives even if you wish you could slash the person's fucking head of. My name is Mercy and it was a very popular virtue name back when those silly white pilgrims were around.
Silly white pilgrims with your names like Mercy!
