Tattoo design for forearm, black ink, Y2K aesthetic mixed with modern tribal style. Flowing abstract tribal lines that resemble skin striations or stretch marks, organic and slightly chaotic. The design should subtly and almost invisibly form the number "333" hidden within the flow of the lines, not clearly readable at first glance. The numbers should blend seamlessly into the pattern, like a hidden detail. Fine line with some bold accents, high contrast, clean stencil, no background.
