Yee is meme originating from the Italian dub of Dingo Pictures' Abenteuer im Land der Dinosaurier/Dinosaurs/Dinosaur Adventure that was edited, focusing on characters Peek and Oro.

The original Italian dialogue is the following (Credit to Know Your Meme):

Peek: Mamma e papa' hanno un nuovo bebe' e non se ne fanno piu' niente di te!

Oro: Yee, come puoi dire una cosa simile, la maggior parte di noi fratelli o sorelle, i genitori amano tutti i figli allo stesso modo.

Here is an English translation:

Peek: Mom and Dad have got a new baby and they aren't doing anything to you anymore!

Oro: Yee. how can you say something like that, the majority of us, brothers and sisters, the parents loves all their children in the same way.

The meme blew up in popularity in 2012 with the original 'Yee' video.

Peek: Mom and Dad have got a new baby and they aren't doing anything to you anymore!

Oro: Yee. how can you say something like that, the majority of us, brothers and sisters, the parents loves all their children in the same way.
