lab rat

One who agrees to let others use him or her as a test subject. A: "Did he really sign up to be a lab rat for some skincare company?" B: "Yeah, because they promised him a bunch of free products to try!" I can't believe I agreed to be my sister's lab rat—now I have to let her practice cutting hair on me.
