Hello Rick although I am from way up North I occasionally reference Cockney Rhyming Slang, so my friend is actually called Terry . The Barnet reference is Cockney Rhyming Slang , Barnet Fair which is Hair in English hence the reference . Barnet is the short form that gets used .I wager your friend Barnet did not do that again in a hurry, captain. Sounds a bit akin to insulting your server or waiter before they bring your food. Not wise.
