When I first heard the word "travelocity" I thought it was a clever combination of two existing words ("travel" + "velocity") that yielded a new and meaningful word. I wondered how difficult it would be to come up with more clever words like "travelocity". Invent-a-Word was born. The best portmanteau word I've come up with so far is cubicle + cleaner = cubicleaner.
Your creative words:
Artemis + mischa = Artemischa
