job blocker
n.— «It’s no wonder that many tattooists themselves refer to them as “job blockers.” How can you take seriously anyone who has a fire-breathing winged serpent / the names of their three kids in sanskrit / the logo of a football team (delete as appropriate) encircling their neck?» —WalesOnline.co.uk (Wales, United Kingdom) Jan. 13, 2009.
