The real life equivalent of undefined behaviour would be driving 
a car out in an ocean, since you are doing something that is 
outside the trafic laws for roads those laws no longer applies.

In a spec, undefined behaviour just means that the program was 
not written in the specified language. This is specific to low 
level languages. The language is the set of all valid programs. 
High level languages checks that the program is valid at either 
compile or runtime. So there is no undefined behaviour in those.
