If you have been fooled/ or had one put over you,or had bad luck the person performing the trick, or passing on the news would say 'scunted'.
If it was a particularly good joke you might say 'scunted badly'
You were caught cheating on your girlfreind.
Your freind might say 'Scunted'
If you set someone up for a joke and they fell for it, when you told them it was you, you would say 'scunted badly'
