Thlabber

This is a recognised scientific term used by wizards to describe the precise instant during any magical transformation where, after a period of feeling elongated, stretched, altered, or reduced to a single point in the space-time continuinuinuum, things have just returned to normal and the subject is feeling the first hints of relief and disorientation.

Sometimes the thlabber moment is relatively benign, as when Moist von Lipwig is subjected to an experimental spell at Unseen University to match him up with the correct library book for his needs. (He got The History of Hats.)

Sometimes, it describes the sort of feeling Angua von Überwald must have on a Bad Hair Day when things have resolved themselves, and she has just morphed into either wolf or human form.
