Occasionally, I've had to use made-up words where there don't seem to be any appropriate real words. Here are some examples:
vulch - To wait for someone else to vacate a parking spot so you can take it, generally getting in other people's way in the process. (Someone who "vulches" is a "vulcher" [vulture].)
encrudded - Encrusted with crud.
redundonym - An acronym, followed by a pointless spelling-out of the last word in it -- i.e., PIN Number, ATM Machine.
Does anyone else have any favorite "personal" words?
