|Zwapo.com -- Zwapo
I like the idea that every page in every book can have a gem on it. It's probably what I love most about writing - that words can be used in a way that's like a child playing in a sandpit, rearranging things, swapping them around.
-- Markus Zusak
"Zwapo" is just one of those non-words that should be a word; indeed, the root word "Zwap" is a play on the word "swap." Certainly, Zwapo would be a great swap meet website or brand for a company that organizes physical swap meets and other trade events.
Also, "Zwap" is listed in the Urban Dictionary as "someone getting hit by an object or person at a high velocity." One sees this word quite a bit in fast-action comic books as superheroes and villains duke it out.
Zwapo is a fast-action term, perhaps describing a screaming fast software program or game -- this term also suggests a techie type word, through and through.
While "Zwapo" does not appear in the USPTO.gov or Trademarkia.com data bases, the term is in commercial use in the Netherlands (See zwapo.nl) for the sales of pre-fab log cabins (Blokhutten). If you plan to do business in the Netherlands and/or sell pre-fab buildings, you might want to consider another name for your business or product. In any case, please consult with a trademark lawyer with any questions you might have about this domain and its potential as a trademark for your product or service.
