The need is clear, and the microbitcoin is a nice sized unit, but a mess of a word/abbreviation.

What's needed is a new word, related to Bitcoin and just as breezy, but with one unambiguous meaning (µBTC) that still leaves plenty of room for appreciation.

My proposal is here:

Ƶibcoin: Your New Favorite Altcoin

Lots of reasoning there, much of which has already been mentioned here, but the TLDR:

  1          bitcoin = 1,000,000    zibcoin = 100,000,000 satoshi
  0.000001   bitcoin =         1    zibcoin =         100 satoshi           
  0.00000001 bitcoin =         0.01 zibcoin =           1 satoshi

...and...

          Ƶ1 = 1 µBTC = BTC0.000001
      Ƶ1,000 = 1 mBTC = BTC0.001
  Ƶ1,000,000          = BTC1

'Zib' can be used as either a noun or verb in casual conversation:

“I’ll bring you a pizza for 10,000 zib”

“when are you going to zib me 10,000 for that pizza Friday night?”

Unless the satoshi is ever made divisible, other new terms won't be necessary. Zibcoin units can be adopted incrementally over time – there's no need for a big synchronized switchover, where old terms change their meaning.

I know it sounds a bit silly, but I think it'll grow on you if you give it a chance.
