Shampoo banana 

Local term for the "twin cities" of Champaign and Urbana in Illinois. These two cities are usually just considered one area, but Champaign-Urbana sounds too formal, so some people just say this instead. People from anywhere else usually don't get it. These people often pronounce the S in Illinois as well.

Ted: Where you live?
Lisa: Shampoo banana!
