How do you use per contra in a sentence?

Per contra is Latin for "on the contrary" or "contrary to", though a little corny yet trendy to use, there are valid English uses for it, for example, "I think it's one of my greatest creations, per contra to what those fools would have you believe..." To use it in a bitter tone sounds very condescending, but Latin is impressive when you want to sound highly educated or intimidating.
