North-Eastern, or Geordie, slang meaning 'come on', 'hurry up' and so on. Voice intonation specifies the exact definition, often not understood by anyone outside of the Newcastle area and thus causes much confusion for non-natives.
/'ha wa/ Used by 'mackems' or people originating from the Sunderland area (North East England), similar meaning and use to the geordie 'howay'. Meaning 'come on' can be used either in the sense of travelling somewhere, or more commonly used at football matches as an expression to get your team to perform harder.
