The most beautiful ass known to mankind. So nice that it will in fact make a grown man cry.

When i saw them onion buns it brought a tear to my eye.

Onion Bun

When the vagina of a hoe resembles a hot roast beef sandwich with cheese on an onion bun from Arby's

Damn hoe! I didn't order no onion bun!
