Justin has been widely popular since the 1980s, when parents were seeking a fresher 'J' boy's name to replace Jason, Jeremy and Jonathan. Now Number 109, it had reached as high as Number 9 in 1990. At this point it's Justin that is suffering from overexposure.
Justin stems from the Latin word meaning 'upright' and 'righteous.' Saint Justin was the first great Christian philosopher, thereby becoming the patron saint of philosophers.
Current popularity is boosted by heartthrobs Justin Timberlake and Justin Bieber.
