"sp" is the boy's word for "blood on the asphalt."

Kazan 1980, when parents struggle to survive, abandoned, unwanted children begin to form gangs, fighting over asphalt. Those who weren't in the gangs were called chushpans. The rules applied to all ages, and the most famous of them was the dangerous "Universam" gang. So you were traveling with a friend to her place, your parents allowed you to spend the night at her place. You get on the bus, just talking and laughing, and then they come on. It's a crowd, the "Universam" gang, and some guys are pushing their coats on you. I think their name is "Zima" (Winter), "Turba" (Vova Marat), and you're wearing a coat. You and your friend tense up and fall silent, just looking out the window. You and your friend can't take it anymore, you get up and sit down in another seat, and Vova, from Adidas, tells you , "Yes, we're actually good."
They smirked, and you and your friend tensed up. You didn't want to get involved with a crowd of guys, especially with a gang.
