In France there is a place wich is name Bretage, and the people of that place don't consider themselve like french. So that song it's directly an offense to the the french territorry
Lyrics
Lorientais, The blood of lands, We still sing, Your sons Lantais, F*ck of suddenly, While was supposed you to kill us, And for the memory, We shall beat, Always by your side, The enemy French people.
