nobba in swedish

We have a word in swedish, nobba, which means "get turned down, being
shown the door, get stood up" with other meanings as well, all of them
bad for one self. The problem is that no dictionary can give an
explanation for the word. I have looked at the english expression hob
nob but even if the etymology of that word is somewhat fitting to "my"
word I feel uneasy over that connection.

Is there a romany word for this which means the same because we have
about 100 words in swedish from romany, many of them from criminal
slang. I´d be very thankful for any suggestion and/or answer you can
give me.
