A developer(s) designs a program/system/spec/whatever to exhibit certain 
behavior. A bug is a behavior exhibited by that creation but which was 
not intended or expected according to the underlying design.
(Design in this context includes the whole source of the program, not 
just architecture, "overall design" or something like that.)

"Unwanted" behavior is not a good definition. A behavior can be 
intended/expected even if is unwanted or undesired. (enhancements, 
behaviors beyond the control of the program, etc.)
