Another term for common code smell
Programmers know immediately what I mean if I talk of finding a 'WTF' in the code base. In particular, it is a noun that refers to an extremely wrongheaded approach/implementation, and not typically an exclamation (though it can be used also as an exclamation).
I don't want to use expressions that thinly veil obscenity, but I can't think of any substitute that communicates this idea quickly and succinctly. Any ideas?
