"Thug Life" Stomach Rocker

The most important tattoo in hip-hop. Probably the most famous stomach rocker in history. Tupac got this tattoo back in 1992 from Dago at Dago's Tattoo in Houston, TX. Pac was allegedly tattooed 8 times in that shop. It's such a brazen tattoo, with a bullet replacing the "I" in life. 

Arguably the most famous tattoo in music.
