Apparently it's called 'Guyliner' and you're a fag and a homo for not being fashionable enough to know this... or so hard-man of London, Danny Dyer, would have us believe, anyway. Doesn't work for Beckham, doesn't work for Danny, doesn't work for Rob Halford and in fact doesn't work for ANY bloke unless they are:
a) Ancient Egyptian.
A supernatural being (vampire, warlock, Goth, etc).
c) Lead singer of an 80s cock-rock band.
d) Any role in a Glam Rock band.
e) Any combination of the above.
I meet three of the above criteria (and met a fourth back when I was a teenager), but still wouldn't be donning the slap without a decent contract and advance payment!!
