Someone who is fun to be around but doesn't like to be around other people. Usually very shy and doesn't like sharing details of one's life. Usually dresses down; in sweatshirts, tennis shoes, etc. Can get angry when being offended and could react in a physical way.
Someone who goes above and beyond what is required. Who sees the larger picture and addresses problems that aren't even known to exist yet.
"Oh wow Dan did an incredible job! I never would have thought to add those supports there, now this thing will last forever!"

"Julia is amazing, have you noticed how every project she touches just goes smoothly?"
"Yeah my dude, she's a real mishunov."
