What does cooked corn mean?

Recently, many boys and girls have received corn maps from the opposite sex, which are still cooked corn. I believe many users don't understand what this means. They ask others with a puzzled face. Girls who cook corn, the pictures of corn are actually earthy love routines. You are cooked corn, cooked corn = belongs to me = belongs to me. Like stalks and buy coke = make love. If you don't want to be a stupid person, write this word in your sister's quotations.

Laugh at me, even if the heavenly king Lao Tzu comes today, it's still corn hahaha ~
