used in examples without context to demostrate logic or concept when variable names are not important. for example, demonstrating if else in python if foo: bar else: biz the code will work if say foo = user_is_authorized #boolean bar = display_page() #return page biz = unauthorized() #return error image opening a production code to fix a bug and insted using proper variable names the person who wrote it used foo, bar and biz.. not cool
