INAPPROPRIATE QUESTION: Can men queef?

Ok, this is a STUPID and CR question, granted. But it has somehow sparked a heated debate amongst me and my sopric friends, so we're looking for a little clarity. Here's the crux of the whole question: What is a queef? Is it a "l fart"? Is the air expelled from a l queef comprised of gas that is produced inside the body? Or is it air that has been "forced" inside the by a foreign object (, , etc.) If it IS air that is forced inside and then expelled, does THIS not also apply to men during gay lovin'? If we define a queef by the ORIGIN of the air expelled, would this mean that a man can queef or is it just for the ladies?
