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.

"You finally pulled a 'happy dragon' didn't you?"
"Last night."
