means Cheap, tacky, or shoddy stuff — or, as a verb, to get yourself tattooed.

from British slang 'tat,' meaning tawdry junk, likely traces back to 'tatty' (shabby, unkempt), which itself probably connects to 'tatter' — rags, loose threads, things falling apart. The tattoo sense is unrelated in root but not in spirit: it's just a clipped, casual shortening of 'tattoo' itself, popularized in British slang. So the word lives a double life — one half about things that look worn out, the other about ink you chose forever while young.
