A brown onion ring is the end result and combination of heat, time, and not wiping one's anus good enough. A sticky, cake-like residue builds up around the anus, which causes a stinky, sandy sensation on the rim of the anus.
I just bought new underwear, and now I can feel a brown onion ring seeping out onto them. Damn, it's hot outside!

Is when you insert your wife's diamond ring in her vagina with the dimond hanging out of her pussy while you fuck her in the ass.
Last night was my wife and I's wedding anniversary, and to commemorate it, I celebrated by giving her the bling bling brown ring!
