A way to end relationships. When you are too awkward or simply cannot be bothered to find the words to break off any kind of relationship. Simply message the person you wish to end contact with the word "Pineapple" and boom! Relationship cancelled. Please Note: you must inform the person prior to your use of the Pineapple Effect otherwise it will be rather useless in this regard.
"Oh, I pineappled that guy. He was so annoying. He kept sending me dick pics!"

"Yeah, love using the Pineapple Effect!"
