The Party Lords by Justin Grimbol

People call him Buttcrack. He's in his early thirties and he's re-enrolled in high school. The other kids think he's a creepy loser. One day a kid asks him to buy beer for his party and Buttcrack figures this is his chance to fit in. But he loses his wallet and the lady at the liquor store won't sell him booze without an ID. To make things worse, his girlfriend won't help and a group of crazed rednecks keep harassing him. But he's a man on a mission. He's determined to party with teenagers. No matter the cost!
