Silly question perhaps, but I haven't a clue.
Never heard anyone say the name, so I tend to see it as a German word, pronounced something like Schl-ah-gge. But probably not, huh?
I think I saw someone rhyme it with engage, but that might just have been poetic license.
Or it could be Schl-ar-j?
Help me please before I say it out loud to someone and get a funny look...
