I was told it is some kind of German saint or something. I understand that the Luftwaffe pilots yelled it when they got a victory.

I have no idea, could you help?

Luftwaffe jagdwaffe pilots half-jokingly adopted Saint Horridus as their patron saint - Horrido being the same.

HTH

Didn't Adolf Galland use "Horrido" as the title of his autobiography?
One of the guys in my IPMS chapter has Galland's autograph on the base of a Me109 model he built., and that is how Galland signed it.

"Horrido" was the title of a history of Jagdwaffe pilots by Trevor Constable and Raymond Tolliver, written back in the 1960's. Actually a pretty good little overview of a LOT of the Luftwaffe experten.

Galland's autobiography was "The First and the Last," and he cooperated with David Baker on a very good biography - "Adolf Galland" - shortly before his death

HTH
