Ever heard of a Cambodian cryptid called a "yet" or "yek"?

I heard a young boy from Cambodia tell a story about demon-giants called what sounded like "yet" but he spelled y-e-k. I can't find information about it anywhere with that spelling. Any ideas?

edit: This is the transcript of his story (keep in mind this is a really hyper ten-year-old):

D- cambodian boy E- his friend

D: Remember that one other creature I talked about last year? What’s it called again?

E: “Yek.”

D:That’s right, Yek. It’s known to be a demon or a giant whichever you guys prefer. The story of the Yek is a giant. Again, it eats humans. It doesn’t matter if it’s a baby this time.

E: Is it hairy?

D: No.

E: Is it ugly?

D: Yes, it is. But yes, these demons they were very… you can tell if a demon was a demon or a human because of their teeth. They will always have paintings on their faces, such as their mouth.

E: Why does it always have to be her?

D: It could be an “it” who knows. Who wants to look down there anyway? Back to the story, if you ever find one you will be known to be dead because it could either become a giant or stay as a human form and just kill you in seconds. The giants, they would eat anything, but the problem was they ate everything besides humans but ever since they found humans they started eating them. That was the strange thing and no one ever tried stopping them. But also not just giant people there were also other giant things, such as giant birds, bigger than the biggest bird in the world and like huge dogs and it would be very creepy if you met one. It’s like you would walk in to the forest and eventually it would be divided between very huge things and very small things.

And yes, it is totally possible that the kid is "yetting" with the teacher. It is part of my job as a research assistant to transcribe recordings from my boss's work with a story-telling club for ESL and immigrant grade school kids. She studies oral narrative and literacy. Often their stories are versions of traditional folklore from around the world, but obviously there might be things lost in translation, or the kid is just completely making it up.
