Nanna Likka Edit Meaning

1.

Indigenous Australian slang. Similar in meaning to mudda likka but implying that the insultee engages in cunnilingus with their grandmother, rather than their mother. It is therefore, a worse insult.

"You ain't no mudda likka, you's a nanna likka!" (Actually heard from the mouth of a 6 year old aboriginal boy, directed at his 10 year old brother, following an altercation.)
