A nickname for a really nice man I know, also a unit of measure.

When you think up something brilliantly righteous while baked.

Y'see, most people see the word millimeter as a way of measurement. However, I see it as a name. A name of a person who is almost like an angel. This is one of the best friends someone could ask for. Consider yourself lucky if you have a friend named Millimeter, because they're quite irreplaceable in every way.
