Dense, irritating, miniature beast of burden

What Shrek screams at donkey out of vexation when Shrek explained to him that ogres are like onions, but donkey kept blabbering on about cakes and parfait.

For your information, there's a lot more to ogres than people think.
Donkey: Example?
Shrek: Example? Okay, um, ogres are like onions.
Donkey: Sniffs They stink?
Shrek: Yes-- No!
Donkey: They make you cry?
Shrek: No!
Donkey: You leave them out in the sun, they get all brown, start sproutin' little white hairs.
Shrek: No! Layers! Onions have layers. Ogres have layers. Onions have layers. You get it? We both have layers.

Donkey: Oh, you both have layers. Oh. Sniffs You know, not everybody likes onions. Cakes! Everybody loves cakes! Cakes have layers.
Shrek: I don't care what everyone likes. Ogres. Are not. Like cakes.
Donkey: You know what else everybody likes? Parfaits. Have you ever met a person, you say, "Hey, let's get some parfait," they say, "No, I don't like parfait"? Parfaits are delicious.
Shrek: No! You dense, irritating, miniature beast of burden! Ogres are like onions! End of story. Bye bye. See ya later.
