A modest toot of ass gas presaging a tuba blast, possibly heralding a morning fart.
I just let loose a warning fart,
To warn you of my morning fart,
It will not be a boring fart,
For all night I've been storing fart.

Get the warning fart mug.
A fart that precedes a bowel movement. It smells horrible and gives you a clue that a stinky turd is soon to follow.
One guy: "Aww jeez, who stunk up the room?!".

The other guy: "Uh oh, I think that was a WARNING FART", with a look of panic on his face as he runs off to the can to take a massive dump.

Usually associated with nasty looking foods, such as breakfast buritos, mexican food in general, or even fast food. After consuming these types of foods, you usually have 2 farts to find a toilet before you have a nasty case of the shits.
