The nostril dance

Why is it that when someone is making popcorn, you catch a whiff and get the as-if-it-were-crack feeling?

But then you eat some and are immediately let down. The popcorn says, "gotcha!"

...leaving butter-prints all over everything
weaseling it's way into the tiny spaces in between your teeth
pasting a film in your mouth, causing water to bead up as you sip
worst of all? those thin shells that hide out inside the kernel suction themselves to the back of your throat (dangerously close to the ever-creepy "hangy ball") and cause you to gag.

It's like petting an adorable animal, only to end up getting bitten.
