iongiafu
It's basically an abbreviation of the phrase "I don't give a fuck". I started saying this a while back after I heard one of Nicki Minaj's songs in which she sings "I don't give a fuck hoe" so then I created this little acronym/abbreviation.
For example:
Linda: Omg Julen look what Mary just said about you.
Julen: What did she say?
Linda: She called you a bitch and she's talking shit.
Julen: Iongiafu
Linda: Omg Julen look what Mary just said about you.
Julen: What did she say?
Linda: She called you a bitch and she's talking shit.
Julen: Iongiafu
