"sideburns and ample bugger's grips"
There are a number of similar phrases all referring to appendages purportedly (careful how I spelt that emoticon) useful to obtain a firm grip.
"Buggers handles" often refers to the fleshy folds by the kidneys which afford a good grip if large enough. I have heard the phrase also used to refer to sideburns. Neither phrase is used in polite society but might be used with colleagues. However the phrase "Bugger Lugs" to mean large (and hence presumably graspable) ears, is used more commonly and in wider society. Also used to refer to someone with big or protruding ears (e.g. Prince Charles aka "WingNut"). Not particularly friendly, as it is designed to mock. Could be used in a soccer crowd to the linesman as in "Oy BuggerLugs! That were our throw-in, not theirs!"
