Often misinterpreted as the acronym for temporomandibular joint disorder, which often results in pain and soreness of the jaw, T.M.J. actually stands for "too many jobs." The jaw is actually sore because the person with T.M.J. has given far too many blow jobs.
"Kortney keeps complaining about her sore jaw, blaming it on her T.M.J., and i couldnt agree more; She gives Too Many Jobs."
