“Kalogeras Sisters and Brother Try Not to Laugh Tortilla Slap Challenge,” the Kalogeras siblings—Jake, 14, Sunday, 21, Demitra, 18, and Eliana, 17—took on the hilarious and competitive tortilla slap challenge. The rules were simple: each sibling would hold a mouthful of water, and then, one by one, they would take turns slapping each other with a tortilla. If anyone laughed or spit out the water, they lost.

Eliana, in a white crop top and skirt, was already giggling nervously. “Alright, Jake,” Sunday teased, “you better watch out because Demitra is really good at making people laugh.”

The first round kicked off with Demitra facing off against Eliana. They both tried their best not to laugh, but Eliana couldn’t keep a straight face, and she burst out laughing just as Demitra slapped her with the tortilla, sending Eliana into a fit of giggles.

But just as Demitra was starting to feel confident, Jake smacked her HARD with the tortilla—right across the cheek! The impact was so strong that it left her in shock, and a little water slipped out of her mouth as she tried to suppress the urge to laugh. “OH MY GOD, JAKE!” Demitra shouted, but she couldn’t help but laugh. And that was it—Demitra lost the round.

Sunday and Eliana couldn’t hold back their laughter either, seeing how Jake had taken charge with his ridiculously strong slap. “Wow, Jake, that was so savage!” Sunday exclaimed through her laughs. “He slapped you into next week!” Eliana added, still laughing uncontrollably.

After Demitra was out, it was Jake’s turn to face Sunday, and this time, he was out for revenge. The two siblings tried to keep their composure as they took turns slapping each other with the tortillas. But the whole time, Jake kept teasing Sunday, making her laugh every time she tried to hold the water in her mouth. She couldn’t keep her cool for long and ended up losing the round too.
