Carter Finally Gets It, by Brent Crawford.
Not only was this book hilarious, it was like a chick lit novel - except for guys, and written by a guy! It's Crawford's first book, apparently, and I hope to see many more from him. The main character, Will Carter (who goes simply by "Carter"), is entering his freshman year of high school, and Crawford really gets into his mind. Simply HILARIOUS and a "must-read." :)
