Ralfploy

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'.
