I've been considering making an account named Bardvark and inverting the black and white of my profile photo....  shhh don't tell anyone. 

Maybe the second account could be for my dark side.  Like a Bizarro (https://en.wikipedia.org/wiki/Bizarro)

Or another thought I just had was:

Maybe Mumbo should be the term for a mili-Sat.  "Smallest" unit available via Lightning.

Example: "Hey tomalies, let me send you a few Mumbo as a zap."

Wumbo

Create a second account with the W turned to an M
