FBO
Acronym for Furiously Beat Off. Not just masturbating, this is when you're going at it like the plane's going down and you have to get off before it crashes into the Atlantic. Also useful when you're on top of a shy girl, or see a super cute picture of cats, pandas, or bears.

Also, something can stand for Furiously Beating Off depending on the context, but honorable men can differ.
"Hey Nick, check out this YouTube video of a baby panda hugging a tiger."

"Excuse me for a minute my friend, I must go and FBO."

FBO
F*** Barack Obama - A phase commonly heard in conservative circles after the messiah gives a speech. Originates from frustration of how to deal with opposition candidate that the MSM is clearly in love with. Can also be used to deal with frustrations that are totally unrelated to Obama, much in the same way that everything can be blamed on Bush and/or global warming.
That guy doesn't know anything about economics. FBO!
