A slang term that refers to stinky armpits on a person who either forgot to use ,or perhaps never even uses deodorant.
Damn, while I was taking a bus tour through Paris, I had to put up with this fatass Frenchman sitting beside me who wore a wifebeater and whose sour onions stank so bad, one would really need to wear a fucking gas mask to be anywhere around him!

A nasty, toxic, deadly fart that stuns and blinds victims as it carries a heavy scent of onion/sour cream and lingers for hours once released. The recipe for this fart is one small bag of sour cream and onion potato chips mixed with a beverage of your choice, let brew in your belly for at least 2 hours and you are ready to release.
Bro, what is that smell, I cant see and I am nearly ready to collapse it is so bad? Dude that is a "Sour Cream and Onion Delight" and yours truly launched that bad boy. Let me know if you want the recipe.
