Breizh Dieub! Breizh Atao!
Kentoc'h mervel eget saotr
What that means?
Bretagne Libre (Independent/Free Brittany)!, Bretagne Forever!
Kentoc'h mervel eget saotr is the motto of Brittany.
Bretagne est hypercool
(I'd say that in Breton if I knew how)
If you say that in Brittany, they'll think you're an annoying Parisian who can't speak proper French and they will advise you to go back where you came from. Just a tip.
You could say Breizh Atao, though it doesn't translate "La Bretagne est hypercool" word-for-word.
