Not the same thing then, after all. Scunnered is disgusted. Also heard it as a noun: 'such and such is a scunner'; that's slightly less common though, and I've usually heard it used that way with an expressive adjective before it.
Sorry to tangentially derail the thread. At least I'm not talking about crotches (about which Mouse is right, by the way (crutch seriously winds me up)).
