Having flavor. This word seems to come from advertisers manipulating words to come up with a concise list of adjectives to stick in the minds of commercial-watchers when they think of the new Taco Bell burrito. They want to convey that it is smoky tasting, spicy, and that it has lots of flavor. Thus they form this word flavory to keep the list consistent. This is another example of how people like words to follow rules and to be consistent, and sometimes they conjure nonstandard formations to have word fit in their surroundings.
