a messed up way of saying "there boy", which is thought to be a saying from the east coast of Canada, but has not been proven as of yet.
person one: Hey man whats up?
person two: O hey der by! just raking some seaweed, you?
person one: what in the hell did you just say?

a der is something you would call a hick. the gods “jansens” and “dpolicatastrophe” invented it as a way to stay “okay” “whatever” “k”, etc. but after it was soon evolved to describe the gods. the ders are in eternal war with the sills.

German for "the". Sounds like "duh", or "dah", so this would explain why "der" is used as "duh" in this day and age. Or maybe because it sounds funnier.
