A Scottish term for the Ayrshire town of Kilmarnock. Local tradition holds that the name of Kilmarnock derives from the missionary St Marnock. It is likely that 'Killie' came from the inability of locals to pronounce or spell 'Kilmarnock'. The term 'Killie' is more commonly used to refer to Kilmarnock Football Club.
'C'mon Killie!' (used to give encouragement to a usually losing soccer team)

'Am fae Killie, no fae Ayr, thank fuck.' (A kilmarnock citizen would use this phrase in reply to an inquiry regarding what part of Scotland they originate from)
