In my opinion, using numbers is kinda derpy.
I would like to see a simple name, maybe 3 different variants:
1. Adjective/Adverb and a Noun/Verb (ex. SleepyChicken, RunningQuickly, etc.)
2. Two Nouns (sometimes separated by 'and') (ex. SmileysAndGamers, DevilCow, etc.)
3. One word, but changing the way it looks or sounds (ex. Guude (lol you might know who this is), Sheiniken (I dunno), Cheval (French), Jope (pronounced 'Hope'), etc.)
Hope I helped,
