I consider a fad tattoo as anything picked out on the flash charts. If you were to walk into a shop wanting a tattoo but having no idea what you wanted, picked one off of the massive flash sheets they have and got it, I'd slap you and eat your children. I can't draw for shit either, but that's the beauty of having a good artist. I go in and describe what I'm thinking, he drafts it, I critique until it's what I want. Just make sure you're the main influence behind a UNIQUE piece and not something everyone and their mother has.
