BFP is usually short for "Big Fucking Psomething". But in referring to relationships, it's a play on words for BFF, "Best Friends Forever". BFP is "Best Friends for Pleasure". Similar to FWB "Friends with Benefits" but better friends and better benefits. FWB is usually a temporary situation, where BFP is more permanent. Like someone in an open relationship might have a BFP. They are your go-to people you trust for regularly having group sex.
That 3-way was the most amazing thing ever, so we're upgrading you from our Gym Buddy to a BFP relationship.

Relationship status that usually occurs prior to cohabitation in which your partners favorite condiments mysteriously begin to appear in your kitchen.
What's Corie's relationship status? I saw a bunch of her Arabic dips and sauces in his fridge. I think he's in a condimented relationship with that Jordanian girl?

an affair where both adulterers work together, are in long-term relationships, and still feel the need to cheat
Family should have always been my priority,
but I lost focus and had a consensual workplace relationship . I'm sorry for any pain that my
actions may have caused to the guys and the
fans but most of all to Ariel. The only thing that
matters right now is my marriage and my
children, and that's where I am going to focus
my attention.

Much like the unhealthy chain restaurant, a McDonald's Relationship is a quick and ready seni-romantic relationship between two consenting adults. Like the "food" from the aforementioned cheap food dispensary, this type of relationship is toxic and the psuedo love experienced leaves your system as fast as your body disposes of a Big Mac from your bowels. The emotions experienced are as nutritious as that dang Mcflurry you like to choke down!,
Jay: Yo, this chick I met in Target like gave me her number and I like called her and applied pressure for her to let me hit dat and she like came over and hit me in the eye with her dick. I then realized she was actually a dude.

Jay: I think I'm a gonna marry him... at least when my black eye goes away.
