We use it constantly in bars in Berkeley. Example:
"The pronouncements of [insert least favorite politician here] do not exhibit the faintest degree of verisimilitude." You can add rhetorical flourish by taking a thoughtful sip of beer immediately thereafter.
Along the same lines is 'verily' - and as you mention, beer (and chin stroking while looking ponderous) is always involved.
"The advent of photography freed painting from the task of verisimilitude, opening the door to a world of abstraction."
