Shamoooze was rejected because it suggested 'sham' and 'ooze' although I think it's catchy, if people could guess the spelling.
We wanted a .com suffix and for some reason two syllables was considered preferable, although I don't think that matters. Directing traffic to your app to create momentum is the crux.

whatavenue.com which could be read 'what a venue' and 'what avenue'
