zero dark thirty

Going completely silent from social networking, un-necessary relationships and distractions until the ultimate goal is attained.

Someone kind of dull, dim, unimpressive, slightly south of mediocre

You know, Joe is kind of a thirty watt bulb, barely got into community college, flunked out after 1 semester as a part time student, now barely keeps his job at the 7 Eleven.
