A Smash Mouth is a term to represent a physically thick
white male who wears a chinstrap beard, over gelled, spiked up hair, and attempts to dress trendy, and most likely thinks he can sing.
AKA Resembles the lead singer of the band Smash Mouth.
He MAY claim to work out
on the regular, however after hitting the gym, he also hits up Hooters with his pals and pounds a few back and eats some ribs to
make up for the pounds he sweat off at the gym.
You all know this typical guy as "that douchebag"
