look up any word, like spook:

when something, e.g. a plan or idea, is full of flaws.
alternatively: when such a thing is both awful and full of flaws.
Alice: ¿Wanna have unprotected sex?
Bob: No thanks, I'd rather not become a teenage father because of that dumbass flawful idea.

Arthur: Hey, let's try assassinating the president with blowdarts!
Betty: No offense, but that's a fucking flawful idea.
