SPF 69 : is a term used to describe the climax of sexual intercourse when the man (doing his woman doggy-style) removes his penis from the vagina and skeets on her back, and proceeds to rub it in... like sunscreen.
Ex:
"He SPF 69'd me before we went out to the beach.""Well then! No sunburns for you today!"
(Xin phép không dịch vì khá là bậy bạ)
Từ này mình biết qua American Pie 4 , Band Camp.
