Abuden Edit Meaning

1.

Same as 'duh'. As in:

Boy says to girl: I am a boy

Girl says: Abuden. Gosh. Boys are idiots.

2.

The short form of "Ah, but then?" to indicate, "What else did you expect?" or "Wasn't that obvious?"

A: I told her I would keep her cat while she went on vacation, but didn't realise I would have to feed the cat.

B: Abuden? Did you expect the cat to go look for food on its own?

See duh, blur, slow, stupid, dumb
