the stevie wonder complex is a complex where you use your hands to feel around for something and not your eyes
tanya: (hyperventilating) i can't find my phone! it's not in my fucking bag!
mike: "let mommy use her fingers" (mike uses the stevie wonder complex by feeling around the outside of the bag and not using his eyes and low and behold.. walla! mike finds tanya's phone then smacks her)
