Street was sitting in the bullpen on his phone, of course. Since it was winter and you felt cold, you took one of his hoodies and pulled it over your t-shirt. After a few minutes, he looks at you and realizes you're wearing his hoodie.

He doesn't like it when people touch his stuff, especially without asking. He rises his eyebrow and says

"Cute. 10, 9, 8..."

He looks at you like he is ready to stab you if you don't take his hoodie off in the next 10 seconds.
