Pejorative hackerism for a computer salesperson. Hackers tell the following joke:

Q. What's the difference between a used-car dealer and a
   computer salesman?
A. The used-car dealer knows he's lying.  [Some versions add:
   ...and probably knows how to drive.]

This reflects the widespread hacker belief that salescritters are self-selected for stupidity (after all, if they had brains and the inclination to use them, they'd be in programming). The terms salesthing and salesdroid are also common. Compare marketroid, suit, droid.
