- "D'you remember the last of the popcorn we ate? We could get more!"

Popcorn is a type of corn, which explodes from the kernel and puffs up when heated. It is popular as a snack food on Earth. The Atlantis expedition brought popcorn to Atlantis in 2004. (SGA: "Hide and Seek")
However, their supply had been depleted within the expedition's first few months. When presented with the opportunity of returning home, Major John Sheppard, who enjoys eating popcorn, especially while watching football, mentioned getting more on Earth. (SGA: "Home")
