Efficient 

Extremely hard working, always functioning at the highest of standards, and finding the best possible solution. Other wise known as a Miriam.

"Oh my god, how did she get all of this DONE?!"
"She's efficient...Duh."

Example 2:
"No no, it takes 30 minutes to get to Whole Foods. There is no possible way for you to get there in twenty minutes."

"Bam! there in ten. "

energy efficient 

Marketing speak for "doesn't work worth a fuck". Only saves any appreciable energy by the placement of the "energy efficient" sticker, which discourages anyone from using it.

That "energy efficient" automatic door takes about five minutes to open, so everyone not in a wheelchair has learned to just open the door the old-fashioned way. Guess it really does save energy! What a piece of shit.

jefficiency 

A jankety version of efficiency where a person thinks that the way they do things is efficient, but in truth, is actually ineffective to a point of incompetency.

Their jefficiency is slowing us down. I can't believe they actually do it that way. It's like saving an email to your desktop for future use that has a link in it. Then opening the email, clicking the link, and closing the email every time you need it rather than just creating a shortcut.
