tattoo flash
Pictures of predesigned tattoos.  Usually a sheet will be about 11x14 and have around 4-7 tats on it all conforming to a generic theme (knives, roses, hearts, etc...).  Usually made to be put into notebooks and whatnot for people to pick from.
RandomGuy: I wanna get inked.

TattGuy: What d'ya want?

RandomGuy: I dunno, lemme take a look at your tattoo flash.

TattGuy: aight.
