The Happy Dragon is when a guy ejaculates into someone elses mouth, and then immediately tickles that person so that they snort the cum out their nose when they laugh.

Over-The-Pants-Hand-Job. Distant cousin of the dry hump.

Similar to an angry dragon.

While getting a girl from behind, when you feel you are about to cum, you spin your partner around, jam your cock down her throat, and make her laugh uncontrollably. You release as she is laughing, causing the ejaculate to pour from her nostrils.

It is said that performing this act will bring you good luck for several years.

During a blowjob, when a guy ejaculates so hard/has a lot of jizz it shoots out of the woman's nose. Here, the woman's head isn't held like an Angry Dragon- it just happens.

When getting titty fucked, and the male ejaculates in your nostrils, blocking your nasal passages, making a loud "thwap " sound, so when you giggle it sounds like you have CHF.
