a racial slur against an italian or italian-american. correcting a definition made previously, italian-americans DO call eachother this occasionaly just like black people use the "n**ga" with eachother. i am italian-american and i do not get offended when i am called this by my otha italian friends but it is pretty insulting when someone not italian says this. so if ur not italian DO NOT USE THIS WORD!
Italian To Italian:
Tony: Heeey! wuts goin on guinea man?!?
Rick: Nuthin much.
Non-Italian To Italian:
Patrick: Heeey! wuts goin on guinea?
Rick: wtf man i will beat ur ass if u say that again!
