crass

       crass (adj.) – coarse; gross; unrefined

for your edification:  Well, that last one was a little crass.  Now I kind of feel like an ass.  You know:  I feel coarse; kind of gross; just unrefined.  Why don’t you do that fun repetition thing we sometimes like to do to remember this one:  “If you’re crass, you’re an ass.  If you’re crass, you’re an ass.”  One more time!  “If you’re crass, you’re an ass!”

examplification -  Mitzi:  The unrefined way you remember the definition for the word crass  is really crass.

Paco:  You mean, “If you’re crass, you’re an ass!”?

Mitzi:  Oh!  I thought you said, “If you’re crass, shove it up your ass.”  Your way is gross, too, though.
