A typo I made once when I was trying to say amigo. But I realized that it's basically fam + amigo, the two most chavvy things to call a friend. So here we are.
Only chavs say this.
Shane: Hey famigo, do you want to go smoke a joint of chavweed in Dank Meme Alley?
Sebastian: Sure fam
Shane: k famigo
sebastian: we r such chavs
shane: lol ikr
