I'm not sure why but there's little that annoys me more than when someone is speaking about something outside their realm of expertise but whose name they know and makes up some wrong, muddled, or "funny" name by which to refer to it instead. Usually distinguishable from genuine confusion by the sarcastic inclusion of the phrase "or whatever" afterwards.

For instance:
- "toki ponga or whatever" (toki pona)
- "open/libre-whatever they're calling it" (LibreOffice)
- "PalmPotty" (referring to any handheld communication device)
