What is the origin of the word "broseph"? Is there an explanation or did it just sound good to someone?
I have never heard it, but it would seem to be a playful portmanteau of "bro" (for "brother") and "Joseph" (a man's name).
"Broseph" is believed to have originated on The Jamie Foxx Show. Braxton (the guy in the red shirt in this clip) often called Jamie's character "Broseph".
