The name Deuce came as an accident: I lend a Korn DVD from my friend and it was called Deuce. So I took a dictonairy and looked for Deuce. Heureka! Here was a proper name for the future puppy. I emailed her breeder explaining what deuce was and the breeder Sonja said it was ok official name for the puppy.
Deuce means 'a face of a die bearing two spots' and
'a playing card bearing the number two'.
Well. That's the story of Deuce. But what about her calling name Piri? I wanted to call her Piru (devil in Finnish) but I didn't have the guts, I was too afraid of getting bad feedback from elderly people :). So I changed the u to i. I can only explain what piri means in Finnish: it's slang word and it means amphetamine. Also, Piri as in piripiri is a chili sauce and man I love my chilis. Maybe one day I have dog named Habanero :D. Or maybe not, because saying "nomen est omen" applies with Piri..
