Melisecond

The measure of time one's marriage engagement lasts. (Suggesting, that it ended abruptly by one of the parties)

That is odd, it seems as though Jason and Melissa's engagement only lasted for a melisecond.

Multisecond 

It is a word that someone with the name Don would use. It is used to describe the amount of time it takes a 22 year old to google something.

Wow, someone at your age should have that information within a few multiseconds.

the oh-fuck milisecond 

The milisecond in between saying/doing something very inapporopriate/embarassing/stupid/racist/sexist/etc and actually realizing what you just said and that fucked up real bad. This milisecond is usually followed by a silence, awkward staring, and you; feeling as though you'd want to just dissapear right away.

-you, telling an mean black joke
-insert the oh-fuck milisecond here
-realizing just a moment too late that your one black friend is there
