beef ghost 

The fart released after consuming way to much beef the night before. These typically are followed by a "beef corpse".

"Cack! What's with the fucking beef ghost? Why didn't you tell me you were hitting up the Korean BBQ joint?"

ghost beef 

The odor of an unoccupied area that suggests someone passed wind there and left, yet the smell remains full force

Also, when the air around you smells like ripe, fresh feces, but you cannot determine where the smell is coming from.

I walked into an empty elevator an it stunk like ghost beef.
