Random

 RANDOM adj. 1. Unpredictable (closest to mathematical definition);
       weird. "The system's been behaving pretty randomly." 2.
       Assorted; undistinguished. "Who was at the conference?"
       "Just a bunch of random business types." 3. Frivolous;
       unproductive; undirected (pejorative). "He's just a random
       loser." 4. Incoherent or inelegant; not well organized. "The
       program has a random set of misfeatures." "That's a random
       name for that function." "Well, all the names were chosen
       pretty randomly." 5. Gratuitously wrong, i.e., poorly done and
       for no good apparent reason. For example, a program that handles file
       name defaulting in a particularly useless way, or a routine that could
       easily have been coded using only three ac's, but randomly uses seven
       for assorted non-overlapping purposes, so that no one else can invoke
       it without first saving four extra ac's. 6. In no particular order,
       though deterministic. "The I/O channels are in a pool, and when a
       file is opened one is chosen randomly." n. 7. A random hacker;
       used particularly of high school students who soak up computer time
       and generally get in the way. 8. (occasional MIT usage) One who lives
       at Random Hall. J. RANDOM is often prefixed to a noun to make a
       "name" out of it (by comparison to common names such as
       "J. Fred Muggs"). The most common uses are "J. Random
       Loser" and "J. Random Nurd" ("Should J. Random
       Loser be allowed to gun down other people?"), but it can be used
       just as an elaborate version of RANDOM in any sense. [See also the
       note at the end of the entry for HACK.]
