Louis doesn't think much of it when his mum and dad ask him for tips on how to be cool.
In fact, he thinks it's pretty funny watching them bump fists and use words like 'safe', 'sick' and 'wicked'.
Until Dad turns up outside Louis's new school dressed like a rapper, that is . . . Suddenly they're trying to friend Louis and all his classmates on Facebook, and wearing baseball caps backwards - IN PUBLIC.
Louis and his best friend Maddy are horrified. Mum and Dad have taken things too far . . . and immediate action is needed!
