Boogregard Shlizetti (often referred to as Boog) is the main antagonist of the Nickelodeon series Fanboy and Chum Chum.
Boog is a short-tempered bully who is obsessed with the video games. He grew up with a video game known as Chimp Chomp (a parody of Donkey Kong), which he plays at the Frosty Mart instead of working. Boog is an enemy of Fanboy, Chum Chum, and many other characters as he likes bopping people, notably any customers who enter the Frosty Mart. This has almost cost Boog to lose his job. For Boog, bopping people was almost like a natural breathing, as it was nearly impossible for him to resist bopping customers despite the many efforts made to stop him.
Boog finally managed to control himself as he confronted Fanboy and Chum Chum without bopping them, only to chase them afterwards.
His voice and his personna are based off of John Travolta. He grew up in a plastic bubble, since he developed allergies from getting out, a reference to "The Boy in the Plastic Bubble". Boog talks like one of Travolta's characters, Vinnie Barbarino from "Welcome Back, Kotter". He likes microwave burritos and ruining other peoples' days, and dislikes when anyone touches or destroys his Chimp Chomp game.
- Due to bopping, his SpongeBob SquarePants counterpart is Mr. Krabs.
