Originally and accidentally created by Marjorie Taylor Greene during a Hooked on Phonics attempt to pronounce indictable. It has since been adopted as a word to describe people who would like to sleep with human men, but cannot on account of their brutal looks. Because with some faces, dicks just can't. Variants include undicktable and undickable.
Person 1: I can't believe Marjorie Taylor Greene is so transphobic when she looks like she was born male.
Person 2: Yeah, she is one indicktable woman/man, whatever.
Person 1: Closest she'll ever get to a dick is her own.
