I think and told by Finnish friends that it means "Oh cunt" (please excuse the use of the C word) but its used everyday out there.
You may have heard
one or two Rally or F1 driver using the term!!!!
Any way I always have a
good gigfgle when watching either F1 or WRC and the Fins say there favorite expetive and the
English airs it all..lol.........if they only knew we knew!!!!!!!!!!!
