The new 'LITERAL Tramp Stamp' from artist Phil Jones is pretty much exactly what you imagined. The temporary tattoo comes from a stamp that is in the shape of a trampoline. Ergo, tramp stamp.
The stamp should be placed on your lower back in the traditional tramp stamp location for maximum irony, but it can be used anywhere, anytime to help spread the joy of the 'LITERAL Tramp Stamp.'
Phil Jones also created a mini tramp stamp that can be carried around in your handbag on a night out, in case you feel that your outfit needs a little "oomph," or if someone looks like they might be deserving of the stamp.
Hopefully more of these hilarious literal tats will be created, but for now everyone can enjoy Phil Jones's tongue-in-cheek tramp(oline) stamp.
