Yunch Planz refers to the catchphrase "Any yunch planz?" frequently heard on the popular TV series 89 Everts, between the two lead characters, Boom and Nala.
More often than not, the use of the catchphrase would transition to the comical duo eating their lunch (or "yunch") at one of the fictional eateries the series featured, including "La Mexicana," "La Cafe du Parque," or "Vaginny Ray's."
Occasionally, the script would call for the yunch planz to be scuttled, leading to a sad scene of Nala crying alone in his office as he eats bad delivery food, while Boom forgets to eat at all. Hilarity ensues.
