Sonic Boom (w) Girl's T-Shirt

A sonic boom is the sound of the shockwaves caused by an object that travels faster than the speed of sound.

In the world of video games 'Sonic Boom' is the name given to the spinning disc-like projectile in the Street Fighter series. This special move performed by Guile (and later Charlie) was his very own answer to Ryu and Ken's Hadoken. Unlike the Hadoken the Sonic Boom, particularly the slow version, had little recovery time allowing the player to follow the projectile putting pressure on the opponent. This became a popular tactic and lead to similar uses of projectiles in other fighting games.

To those who still "Sonic Boom", we salute you.
