I would really appreciate someone explaining me the phrase in the following passage from the "The Ant King" story written by Benjamin Rosenbaum :

...Sheila switched to MTV and sank into the couch next to the AntKing.
“Hi,” said the Ant King drowsily.
“Hi,” said Sheila.
“Hey, I missed you,” said the Ant King.
“Stick it in your ear,” said Sheila.
“Listen, your ambivalence about me is really getting old, Sheila,” said the Ant King.
“Ambivalence about you? Dream on,” said Sheila...

Is that an idiom? If not then what does it mean?

'Stick it in your ear!' is indeed an idiomatic epithet meaning 'I don't believe you so shut up!'

It's a rude and aggressive way to tell someone that you don't want to have anything to do with them.
