An extremely frugal individual, caring not for any interests other than his own when in the company of others. One who will seize assets belonging to others whilst on holiday. A 'three times tea bag user', One who 'waters down the milk'. A frequent unwanted visitor. 50 pence head.
That fella wouldn't give you the steam off his piss... He is as tight as a 'ralfploy'... Or, It's minus 6 out there, turn on the heating - you are as tight as a 'ralfploy'.
