A bold tattoo that's tattooed on top of old, faded, or soft tattoos with little regard for them. NOT a coverup, where the goal is to completely cover up the old tattoo and try to make it look like there was nothing there before using calculated shapes, dark shading, and bold saturated colors. A blastover doesn't care if you can see what was there before, as long as it is black and bold enough to steal the focus. The tattoo(s ) you had before become a subtle and unimportant background for your new powerful tattoo.
' I really don't like my sleeve anymore, it's too colorful and hard to make out what's going on, I think I wanna get it covered up.'
'Covering up a sleeve, would be very diffult and expensive. Even if you just blacked most of it out. Its all faded and soft, why don't you just get some blastovers? Just ignore what you have and tattoo bold, black tattoos on top of it, that garbage sleeve could look real dope as a background for some heavy tattoos, like you don't give a fuck though.'
