Pronounced like "wood". It's how the word good sounds to someone when you ask how their food is and they answer you with the food still in their mouth.
A man who is ample in both intelligence and physical appearance, not just one or the other. A goob must be smart and capable, and very attractive. Goobs are almost always slender, though not necessarily hard and wiry - more of a lanky look to them. If he wears glasses, contacts, and/or has braces, then that is a bonus to their goobness. Also, goobs are kind, patient, and shy. You may have to approach the goob first, but once you get him talking... it's destiny.
