After a guy has sex and is too lazy to take a shower, he washes his balls in the bathroom sink. To do this, he climbs up and begins balancing himself on the sink...splashing water on his nuts and mimicking the Saturday Night Live character Mango's mannerisms and noises in front of the mirror.
Usually works only with 1 nighter's, which is self-explanatory.
After I got done fucking, I was too drunk to take a shower, but I did The Mango and now my junk is clean.
I did The Mango after I fucked this chick at the club, now she doesn't now if I was joking, or I'm certifiably retarded.
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: Hey Eric, lets do the Mango.
Eric: Hell yeah biatch, your house or mine?
William: Lets do it on the roof of the school!
Eric: HELL YESSS.
