What if you mix the ketchup with mayo and mustard? Am I still a bitch?putting kechup on a burger is a lot more disgusting than putting mayo on a burger. It doesn't even work with red meat. It was started in the 50s to get kids to eat burgers. So basically anyone who puts ketchup on a burger is like a 5 year old.
