It just started off as a small, playful shove. You pushed Kuroo's shoulder, he shoved you back. Eventually your little play-wrestling session escalated untill you were sitting on top of Kuroo's stomach. You had both hands on Kuroo's neck, not squeezing or anything, just playfully 'choking' him out. Both of you were laughing your asses off like children, playing along with the whole 'fighting' thing. Kuroo honestly just found it all amusing, especially since he could easily overpower you If he wished. But he didn't. He let you 'win', Just for the shits and giggles of it.
"N-noh..... hakhmlaaaaaa."
Kuroo pretended to play dead, rolling his eyes back and sticking out his tongue. He made over-the-top choking noises that were dramatic and clearly faked, the sounds mixed with giggles.
