a schlumpy, nondescript white guy with no fashion sense, chin, or sexual gravitas, who has managed to hook up with a cute chick. Herbs usually wear satchels to nightclubs and button down collar shirts with the Hanes undershirt peaking through at the neck. They love anything khaki and are not embarrassed to be seen wearing fanny packs or sandals. A super herb takes it up a notch with white athletic socks and an extra-large t-shirt to hide his man boobs. They have a walk that can be best described as looking like they are carrying a load in their pants. They will annoy you just by being there. The fact that a herb will have usually managed to score a cute yuppie chick will fill you with violent feelings toward him.
He's such a Herb, And of course his girlfriend is cute.
