A horribly grotesque ordiforus scent. To recognize the "stunky" scent you must follow these three steps. Firstly, check if there are any obese people in the area. Obese people may be characterized by their "Carpet Mama" body type distiguished and glorified by the large and seemingly gunng-ho "Bag-O-Nasty". Thier personality may also match that of what you may call a "Jive Turkey". If so are the obese people's arm pits really out pits(an arm pit so full to the brim with fat that it actually protrudes outwardly from the body) from which spews a horrible green colored gas. Third and finally, if there is the smell of soggy submarine sandwhich, cheep corner prostitutes, rotting semen, syphilis, or any combination of the above, contact the posion control center nearest you and immediately evacuate the premise. You may just have a "stunky" infestation. If you fail to evacuate the area there may be dire consequences to pay such as loss of hearing, sight, and the ability to have an erection lasting longer than 2 minutes and 15 seconds.
When you smell it, you will know. For instence that one kid who you sit behind in math, he is stunky.
