A fictional significant other. That is, a boyfriend/girlfriend/spouse, one that a friend frequently refers to, that neither you nor any of your friends has met. Refers to the slang boo as a sig. other, and, obviously, a reference to the secretive, mostly-hidden character in the novel, To Kill a Mockingbird.

The act of randomly throwing up on the bed while sleeping. Oftentimes it is a long time before one notices the actual puke, even after waking up.
