Lishp

Lishp: noun. A lishp is a quite uncommon speech impediment that manifests itself in a manner almost exactly opposite to a lisp. While a person with a lisp usually can´t make the sounds "s" and "z," a person with a lishp can´t make the sounds "sh" and "zh" (as heard in the words "ship" and "courgette"). A possible cause of this impediment is the lack of a tongue, teeth or mouth, but also the inability to raise the front of one´s tongue to alter the way air exits the mouth. It has been proposed on several occasions that the words lishp and lisp should switch their meanings in order to make them pronounceable by the people who possess them, but these plans have been sabotaged every single time by some inhumane monsters that are evidently amused by scenes where people with lishps and lisps try to explain their diagnoses to others and fail every single time as they are confused for their lisp or lishp possessing counterparts.
