It's called a sloppy joe or a messy sammich. bbq on a bun and slush burger is blasphemy!
In all reality, they should be called "sloppy - insert name of person making them". Sloppy "Joe" only if a person named Joe made them. So we have "Sloppy Tommyboys", "Sloppy guywhofishes", "Sloppy juanrs" etc. Just go home tonight and say to your wife that you want some "Sloppy Karens", or "Sloppy Sarahs". See how far that gets ya.

Its a slushburger, manwich is gross, ketchup and mustard with a little brown sugar mixed in with the burger and onions is suprisingly good and costs about a nickel.
