I have recently heard the phrase bugger-lugs used to refer to a person present, as in "How much do I owe you, bugger-lugs?". I have also heard it used to refer to a moderately mischievous child ("what have you been up to, bugger-lugs?"), and I can also remember my mother using the phrase to refer to the cat, in the same way as the mischievous child.
But does anyone know where the phrase comes from? I have tried a search and found the results here, which doesn't shed much light on the matter. Green's Dictionary of Slang suggests it is an affectionate term of address, usually among men, and hints at a naval origin, but otherwise sheds no light on the matter.
Edit following Hugo's link produces possibly an alternative meaning:-
"Well known in 40s / 50s Lancashire. For many years I thought it was 'bug-a-lugs', never having seen it written ... gross or corpulent habit' from fusty + lug.('lug' in the sense of heavy or slow) Perhaps from buggy-lugs or bugs-in-lugs?"
