Bro, you know the hot girl next door to me? The girl is so horny and wild in bed man! I fucked her last nite and she kept on yelling SMAF me baby SMAF me. I was fucking her doggystyle n spanking her fine ass so hard. The sound we made was great sex music, it was like PAP! fapfapfapfapfap PAP! PAP! PAP! fapfapfapfapfap PAP! Then the girl said oh yes SMAF harder. I love it when a man takes charge n takes good care of business in bed. Be a strong cowboy n SMAF me. Im like damn man the chick’s damn fucking wild man. Im just lucky.
As well as being a conjunction of "smart fuck," smafuck is also:
The act of brown-bagging a woman, otherwise figuratively "cropping out" the woman's face prior to and during intercourse, as the term is derived from "smaf," hence "smafuck."
