A term for a boy or a boy's interest in you. The degree to which they match the decor of your front room reflects how well they fit you. Origin: Little Red's Vignette. Variation: Heinous Green houseplant. This is the leftover plant from your 8th grade science experiment that you watered with Fresca just for kicks and didn't really expect to grow. You thought you'd just amuse yourself pushing the seed around endlessly in a pool of soda, but low and behold, here is a heineous green houseplant staring you in the face. In short, it's the boy you thought you were harmlessly flirting with, but come to find out, you have been leading him on. Origin: personal experience.
