Basically, the movie is just a bunch of ridiculous crap that sets up other ridiculous crap.
The main character, Napoleon, goes to high school and lives with his brother Kip and his grandmother. Napoleon has curly hair and glasses and says stuff like “Whatever I feel like I wanna do, GOSH!” and “A frickin’ 12 gauge. What do you think?!”.
Kip is 32 years old and sets on the computer “chatting with babes” all day. He has an online girlfriend named Lafawndah, but she isn’t shown or anything until later.
At school, Napoleon befriends the new student from Mexico, Pedro. When their grandmother injures herself while riding in the sand dunes, Napoleon’s uncle Rico is called to take care of them.
Uncle Rico is a huge jerk. He starts selling Tupperware with Kip, and throws a piece of steak directly at Napoleon’s face while he’s riding Pedro’s bike.
Earlier in the movie, this girl named Deb came and left a bunch of her art crap after failing to sell it to Napoleon. At some point (I lowkey forgot the order of events

) Napoleon talks to her about it and gives it back, and Pedro asks her to the school dance. After the dance, Pedro decides to run for class president against a girl named Summer.
Some time later, Lafawndah comes to visit, and he encourages Kip into wearing gangster clothes and saying stuff like “Peace out”.
Napoleon starts practicing dancing. Uncle Rico blatantly lies about Napoleon and is a creep to Deb, causing her to stop being friends with Napoleon.
Near the end, Pedro has to have a skit ready for some candidate speech, but nobody told him. So Napoleon plays a tape he has and starts dancing on stage while wearing a shirt that says “VOTE FOR PEDRO”. Everyone cheers and votes for Pedro. His stunning performance causes Deb to be his friend again. When they meet each other again, Napoleon drops the banger line “I cought you a delicious bass.”
Kip moves in with Lafawndah and marries her two months later. At the wedding, Napoleon rides in on a horse that he tamed and Kip and Lafawndah ride away on it.
