The idea is to mention 2 things/people that you get confused between. It can be legitimate, as in my case, "I get confused between Robert DiNero and Al Pacino" or “I get confused between Leelee Sobieski and Helen Hunt” or “I get confused between sweet potatoes and yams”, or “I get confused between Christina Aguilera and Brittany Spears”,

OR, you can “get confused” between two things that are silly/semantically similar as in "I get confused between Roma Downey and Morton Downey Jr." The next person could say "I get confused between Morton Downey Jr. and Robert Downey Jr." and the next person might say "I get confused between Robert Downey Jr. and Downy fabric softener". . . Or, taking the Brittany Spears example above, you might say “I get confused between Brittany Spears and broccoli spears”.

It is supposed to continue on in a link, someone is confused between thing A and thing B. The next person is confused between thing B and thing C. The next person is confused between thing C and thing D and so on.

I get confused between baking soda and baking powder
