Ahhh, thanks to my close and personal friends at Dictionary.com, I have the offical definition:
1. Any of various stages in the development of a plan, document, or picture: a preliminary draft of a report; the final draft of a paper.
2. A representation of something to be constructed.
And that definitely sounds like something Gabe's Mom would be into... either that, or "The process or method of selecting one or more individuals from a group, as for a service or duty," or "The act of pulling loads; traction. Something that is pulled or drawn; a load. A team of animals used to pull loads," or "A gulp, swallow, or inhalation, the amount taken in by a single act of drinking or inhaling."
There- that's what you get. 'Your Mom' jokes from Dictionary.com.
