I am British and I have heard and used this phrase (except it is “lefty loosey, righty tighty” because that order makes much more sense).

Righty Tighty, Lefty Loosey
Jason Slater
Published on Sep 22, 2014
When I was confused by the aphorism “righty-tighty, lefty-loosey,” my father taught me the phrase, “Time is always tight.” Learn why the linear idea of right and left makes no sense when dealing with a screw that turns in a circle. A better way to think about which way to turn a bolt is clockwise or counter-clockwise.
