munchkin

/muhnch´kin/, n.

[from the squeaky-voiced little people in L. Frank Baum’s The Wizard of Oz] A teenage-or-younger micro enthusiast hacking BASIC or something else equally constricted. A term of mild derision — munchkins are annoying but some grow up to be hackers after passing through a larval stage. The term urchin is also used. See also wannabee, bitty box.
