Test balloon

This one was heard on that malaphor filled show, All In with Chris Hayes. It is a mashup of “trial balloon” (a tentative execution of a plan to gauge the interest or approval of someone else, usually the public) and “acid test” (a decisive trial to determine worth or quality) or perhaps “litmus test” . “Test case” (a legal case which is used as an example for deciding other similar cases) might also be in the mix. The malaphor can be heard here:

A big thank you to Frank King for hearing this one and sending it in!
