Pineapple

A safe-word for when someone derails your conversation because they didn't get your reference.

Culprit: "My friend says it's been raining since November 5. I hope it's stopped by the time we arrive."
You: "Remember, remember."
Culprit: "What, was there something on the weather today?"
You: "Don't know, I haven't checked."
Culprit: "You mean I'd better remember to bring my umbrella, huh? :D"
You: "PINEAPPLE! PINEAPPLE! THIS CONVERSATION MUST END!"
