Got The Boost Boys 

A classic Sidemen catchphrase said when a GTA race starts, and one accelerates.

Believed to be first said by Behzinga in February 2014 in the video (GTA 5 FUNNY MOMENTS | "LAWNMOWER TIME" | w/KSI, Zerkaa, Vikkstar, Wroetoshaw & More!)

Got the boost boys 

A saying you shout before a gta race

Simon is still saying got the boost boys even though no one he plays with knows what he is on about
