I would have to slap up my 15-year-old self.
Id tell him quit fukking with sports and gym class, you'll never be an athlete and there are some babes you could chop up instead of playing 21
Id tell him quit being a bytch. Can't get any p*ssy acting like one.
Id tell him to stay out of the casino because we got an addictive personality.
But id let him know, you lose your virginity the next year, enjoy the 19-21 years old because you're gonna be around some fly girls who like to get drunk. Id also tell him to stop wearing Jerseys and matching hats.
