bonerologist

noun. A student of the stiffy.

Real citation: "I think if my boner went away for 10 months, I would go to a urologist or a boner-ologist. That way I could get it up. But then I'd be afraid that anything, including packets of ketchup you get from McDonald's, would induce a boner the size of Utah."

Made-up citation: "Indiana Jones said, 'Don't bring a knife to a gunfight.' In my family, we say, 'Don't bring a bonerologist to the senior prom.' My family has problems."
