Someone who responds to an ad for
something (usually a car) on a website (usually on
Craigslist), and takes up your time checking it out, claims that they will buy it, only to
disappear.
Nick: Did you sell that car yet?
Brian: No, that guy that came by was a total ball sniffer...he never
called back...which sucks because I told another guy it was sold already.
Nick: What a total
handjob!
Let's kick his ass if we ever see him again!
