stuffed onion 

A stuffed onion is a booty so round and tight that it brings tears to your eyes

I am not fundamentally opposed to junk in the trunk, although my preference is a stuffed onion over an oozing pumpkin.

I gave her a Preston Onion. It smelled terrible but she loved it.

My boyfriend gave me a Preston Onion and it made my farts smell great for 3 days.

One time, at band camp, I gave this one chick a Preston Onion and she shat it out her mouth 15 hours later.

Sour Cream and Onion Delight

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.
