Really? O.K. B.O. is a double entendre "a figure of speech in which a spoken phrase is devised to be understood in either of two ways. Often the first (more obvious) meaning is straightforward, while the second meaning is less so: often risqué or ironic.
B.O. obviously, from the context, stands for Barrack Obama. B.O. is also an acronym for body odor. I've been using it since back in the day when you couldn't call him BHO, because is was forbidden to remind people that his middle name is Hussien. If we were limited to referring tog him Barrack Obama, I elected to do so in way that his supporters wold not appreciate.
Let me know if you need sarcasm explained to you also. Many Birthers do.
Only at huff and puff. Which is where you belong.
Q. If our goal is to see that Obama does not win in 2012, why would you discourage birthers.
A. You are a lib.
