Simifferent 

Similar, yet somehow very different.

"You are a beautiful, put-together, successful woman and I am a creative, struggling, mess of a man with excessive body hair, but we both sit on exercise balls, love box wine, our favorite color is green (then yellow) and we have pooed ourselves as adults."
"I guess that makes us simifferent."

snifferentiate 

To sort items with one's nose: can apply to prospective dates, food items, and of course, dirty laundry.

Beavis spent all morning going through the hamper, but could not snifferentiate which pair of boxers to wear to his sister's wedding.
