To spontaneously get in a fight and throw down, but also mutually and organized. At the end of the fight, there are no harsh feelings for each other, because it was a two-way agreement.
EX. 1 - Dude, this rando was calling me out on the streets last night, calling me offensive names. I didn't like it, so I asked him if he wanted to sanction. He complied...I fucked him up...good night of sanctioning...unprovoked of course.
EX. 2 - Dude, I was being a huge asshole to rando people last night. I was trying to pick fights and everything (slapping, hitting, etc.). Well guess what? Some guy who I tried to pick a fight with called me out. He asked me if I wanted to sanction. I said yes...bad idea.
