When two people reach into a bag or bowl of popcorn at the same time, and their fingers touch. Thought to be the equivalent of "love at first sight", but only with popcorn.
"Yesterday, I went to go see the Hunger Games with Liam... We both reached for the popcorn at the same time, and... well, I could feel our popcorn connection!"

"Awww. You two must be made for each other! You have so much in common!"
