Since you're from Argentina you know that the word negro which in english means nigga or black, sometimes is used here in a friendly way, it's like say friend, mate, however it seems this is not the case and it was used with disrespectful intetions. The translation of paradoxx is not so good so i'll translate to avoid inconsistencies.
niko78: cry black fag guys
niko78: common nigga your saw and your anus ''mama vergazo''
niko78: I like/love bolivian poop (making reference that bolivia is poop)
I can't ban because my mIRC is fucked up so someone do the honors for me :p
