The annoying, large raised bumps on your skin(usually on the legs or arms, but if you're a streaker, it can be OTHER places as well), that are symptoms of an allergy to a nearby object. Allergy bumps itch like hell, and are impossible to resist scratching, only further irritating the affected area.
The average allergy bump is notably larger than a zit, but about half the size of a dime.
