That thing above your head as you sleep that protects you from the weather and flying monkeys. Not to be pronounced "Ruff" because only someone from the south with low levels of education would say something that asinine.
"Hey go up on the ruff", "What the fuck is a ruff you ignorant yankee?".

"I hear Santa on the roof" , "No Santa does not love you".

4.
A simple expression used by Epsilons (derived from a portion of the novel Brave New World by Aldous Huxley). This term comes from an Epsilon Semi-Moron elevator worker, who when asked to move the elevator to a different floor, simply replied "roof?". This phrase is most commonly used in question form but can be used to respond to any question or statement.
Where the hell do you think you're going?
-Roof...

Ok everyone, class started three minutes ago so get in your seats. Lexi and Charlie, that means you too.
