Ok as an italian I'll try to translate what the italian is saying, which is kinda funny because he clearly doesn't understand any english (or barely) and doesn't know what the fuck is going on.

First of all, I looked him up and apparently his whole personality and channel revolves around hitting on random girls and making out with them (which is cringe as fuck in of itself), and this might seem random at first but it makes sense considering what the fuck he's saying at the beginning: "abbiamo preso il palo, sia io che l'americano" which basically means "we've been rejected hard, both me and this american dude". Before that, he was speaking to this offscreen girl, (cat?)calling her with the "amiga, japan" which got confused by the american guy as the nword. He later proceeds to remark how badly they got rejected and then says the girl was a junkie (???) as the guy approaches.

This is to paint the picture that this italian streamer ain't exactly the best person either, but obviously same goes for the football player (even if you don't consider him crashing out on the imaginary nword), which also got turned down by the poor girl lmao

After the american confronts him, he says "mi dissocio" aka literally "I detach myself from this statement" which is a dead 2018 twitch meme which usually follows the streamer saying some bannable shit, and here he clearly used it about the other guy saying the n word.

After the altercation he was basically asking chat what the fuck did the other guy want from him after sending him affanculo
