Pu In Sai
A Hawaiian slang referring to sexual intercourse; to "put inside." Coined in 1993 by the late Hawaiian recording artist Israel Kamakawiwo'ole.
You know, when you get all horny and you get the kickstand and you like pu in sai? Well, the safest sex is no sex. Not the plastic. So no pu in sai.
