Icular ick-You-liar noun 1. A species of extremely picky organisms that successfully conquered earth before realizing that it was beneath their standards. While experts hold that the thought of crossbreeding between our two species would turn any Icular's digestion-sack, rumors persist that such unions did or do take place and that these offspring remain among us to this day. "I've been thinking... You don't like the way I look, you don't like the way I talk... seems to me you're part-Icular..." -Cuesto, Vincente. "They Judge Among Us".
