An acronym for Bareback Full Service. A term generally used within online escort/prostitution communities to refer to unprotected (condomless) vaginal sex with a prostitute. The term also encompasses unprotected anal sex, and is sometimes used to describe non-prostitute (civilian) sexual encounters as well. Considered the holy grail by some Johns(customers), and frowned upon (at least publicy) by others. Most mongers (another word for John) are guilty of bbfs at least several times in their lives.
In the heat of the moment, I jammed my dick in the prostitute bareback without a condom and came in her pussy. After the bbfs, I got tested, and luckily I came out negative for STDs.

Bbf means boy best friend. Your boy best friend is a boy you can trust as much and you can trust your girl best friends. You go to him for advice about boys and he goes to you for advice about girls.

You both deep down inside love each other

Having a bbf means you can be in a relationship and that not be cheating. It’s friends with benefits really. Bbf can meet your parents bc it’s not your boyfriend. To keep the bbf boundaries don’t try to have a relationship. Unless you both agree to take it farther than friends.
Girl bestie: “ I need me a boy to talk to but I don’t want a relationship”

Other girl bestie: “you need you a bbf. You need one you can trust. And love without catching feelings”

BBF stands for Bestest Best Friend. It is a special term used only to describe those whom you trust with your every secret and private thoughts. To become awarded the title BBF is to completely earn the trust of giver of that title. BBF's are inherently perfect. Those titled BBF's can have no flaws.
