Mark Weins.
TL;DR: Mark Weins makes movie-length videos where he eats slop, pretends to love it, gives zero information on what he's eating and describes the food with the eloquence of a 5 year old. All while staring at the camera with his eyes bugging out of his skull.
He makes 40 minute videos where he goes to third world countries and eats slop.
Every video is the same:
"Hey everyone it's Mmmark weins (he has a weird thing where he hangs on to his Ms) and today I'm in beautiful Bummmfuckistan and I'm going to be treated to a feast in the village of Oog'buka."
He sits at a tree stump, they bring him a plate of brown slime, green slime and some bread.
"Oh woow! Ha ha ha ha (he has a really fake, annoying staccato laugh) this looks soooo good! Ha ha ha ha." He points to the brown slop. "This is the Gb'uk Talan" points to the green ooze "Aaand this is the Balop" (he names foods and doesn't explain what they are.)
He shovels the brown slime into his salivating maw with his hands.
"MMMMMMMM!" He leans over in pure, fabricated ecstasy. His eyes bug out of his head and he brings his gormless face within an inch of the camera. "That is sooo good! The flavors are so intense and they work together so well! Ha ha ha ha you can really taste the Huluk and the Co-riander (he has this verbal tick where he pronounces coriander like a pajeet)."
He takes another bite. "Ha ha ha ha. It's sooo good, and it's not sweet (for some reason the highest compliment he can give a dish is that it's not sweet), and the FLAVORS. The FLAVORS are so-INTENSE- Ha ha ha ha ha. Aaand it's NOT SWEET- Ha ha ha ha ha ha. It's sooooo goood! Ha ha ha ha ha."
Every few words he thrusts his head into the camera like a cobra threatening a hiker that got too close. Eyes ready to fly out of his head. Never breaking eye contact. He laughs again. At what? Who knows.
This goes on for 40 minutes.
