When you initially meet someone and do not expect the introduction to take 3 hours and 20 minutes to include facts about math, botany, PHD's, teaching, cat urine, only children, virgin mds, OU, and other useless crap.
I met a very nice person at a cocktail party. He asked if I knew this hot chic who was watching college football; she may be the girl of my dreams. I told him her name was Holly. Then warned him do NOT do it! You will be Cassiefied.

To assert your stories into a person's mind; not allowing them to exit the gruesome conversation until you are finished. Or, making awkward jokes that mean nothing, also asserting them.
The other day, I totally Cassiefied John...He will never be the same again...
