When you try to make a phenommelette but can't risk flipping it cus it might fall apart, so you chicken out and tell everyone you made frittata. You're trying to cover up an ommelette abortion. You're a shit person and you should quit earth right after you finish eating that Shittata.
(From kitchen) Oh shit..
what happened, is the ommelette okay?
Errm, what Ommelette? There's no ommelette, I'm making frittata.
Just flip the thing you pussy, I hate Shittata!
Not an argument and not exactly neutral territory, a shitata is a phase of interaction where shit is flung but the friendship is not over. Going through some shit with someone, basically. Can involve more than 1 person: the shitata is usually a grander scale shit slinging fest between multiple people. Like a brouhaha, but more catty.
Billy told Mary that Jane said that Esther was a total slut and now Billy's in the doghouse because Jane is pissed that he told Mary anything about her opinions of Esther. Mary told Annie & this all got back to Esther, who isn't talking to Jane anymore. Pfft...what a huge shitata!
