Whinging in engilish over here is usually what children do:they go on and on in a whining voice about something .This is usually something they want and you are not prepared to buy but it can be complaining about a hurt.In my book to say somebody is whinging is not very nice

By the way in this part of england we eat pasties:they are a special form of pie.I mention this as it always causes non U.K residents a laugh.
