bar-code hairstyle
n. A style in which a man's last few strands of hair are combed across the top of his head, thus resembling a bar-code pattern.
Don't mistake Bruce Osborne for a social crusader or a parenting expert. He just tries to be a good, fun dad. I do have a question for Mika though: If she thinks her father, who wears shorts and shades and takes pictures of SMAP for a living, is uncool, how would she feel if he sported a "bar code" hairstyle and pushed papers at the local ward office?

Bar-code hairstyle (baakado haasutyru): A term used by Japanese university students to describe male professors with thinning hair who comb what few tresses they have left over their bald spots.

When Arthur Scargill rose to speak at the conference yesterday, he caught his braces on a doorknob en route to the podium and yanked himself back to an era when coal was king and he was on the throne. ''People keep telling me,'' he screamed, apparently unaware that the black tube pointing towards his mouth was a microphone, ''they don't want to go back to the 70s. I'd LOVE to go back to the 70s.'' …

Scargill has kept not just his 70s bar-code hairstyle but also his 70s vocabulary in trim. The Government is waging an ''ideological war'' against the unions. ''Get off your knees and fight back.''
