Translation: Stop Complaining/ being cheeky/ you're disgusting Depending on what area you're from, you'll probably call someone a scunner if they're either complaining about something and you want them to shut up, they're pushing the limits of how far your patience reaches and they're being rather cheeky; or they basically make you feel a bit sick, in which case, calling them a scunner reminds them that they're a bit of a cretin. Either way, you want them to disappear from your sight.
