prefessional

When something is not done professionally, but rather in your own garage... terribly. And yet, somehow, it works.

I can totally weld that hood onto your civic dude. I'm a prefessional.

customazing

An item that is customized, and amazing. But in a bad way. Generally said item is not of high quality, or produced by a high caliber individual.

Wow, Ted! that krylon paint job on your Ford Tempo is customazing!
