Jack Horowitz

A Jack (Or know by his friends as Jaquavion) enjoys the casual fratboi whiteclaw, Jack's top of his head looks like a distorted brown genetical error. Jack Horowitz is the biggest fratboi wannabe in ELA class Jack tends to write and ramble about his ambitions to become one. Jack also the biggest car fiend and cannot stop obsessing over his grandpa's 1776 Declaration of Independence Limited Edition Corvette.

Oh he's such a Jack Horowitz off.

Jack

The most wonderful guy in the world. He's a literal angel, a literal light in the form of a human. He's a great person, a true gentleman, who has amazing jokes. He's adorable and sweet, and an overall really awesome person. We should all be very happy he exists, because he's the best person in the universe.

Jack is an angel.
