The Mango is a sex move which originated from north korean immigrants who escaped from NK and travelled to Hong Kong on immigrant boats. The people who perform this sacred sex ritual are banned from entering either South Korea or North Korea due to their exccesively high gayness levels. Better luck next year guys.

William: Lets do it on the roof of the school!
Eric: HELL YESSS.
