knife to split

Cut a knife in two, shove one end in your peehole and the other in your anus, fucking wildly back and forth.

So Jon was into some weird stuff, dude decided to perform a knife to split and needed Sarah's friend, Katie to join them. Katie willingly accepted as she was a bit of a urethraholic, but we'll get into that another time. He decided to go handle first on both sides, producing the knife blade ends' for his ladies. He got into a back and forth humping motion slaughtering Katie while she tried to suck his dick, turning it into a wildly bloody and gratuitous event. Sarah, on the other end, handled it like a fucking champ and went ass to ass with Jon until climaxing at a G-spot orgasm for several hours. She wiped her booty and rubbed the dirtied cloth on Jon's face asking, "Is that all you got for me, babe?"

Bringing a Knife to a Threesome 

Pop culture euphemism for;
1. Person(s) who kills a good mood, fun killer, party pooper
2. Bringing a highly inappropriate item ill suited for the situation.

Origin:
Based on this ridiculous account;
"In Fargo, N.D., a man, 33, reportedly stabbed another man, 37, during a threesome. The stabbing allegedly occurred when one of the men reportedly refused to switch positions during the sexual romp."

The expression bounces off the old adage Bringing a knife to a gunfight.

"Ah shit, don't invite that guy! He'd bring a knife to a threesome".

"His friend was known for bringing a knife to a threesome, so he wrote a list items they would need; better safe than sorry".

"Who brings a knife to a threesome!? Seriously!"

addiction to the knife 

An obsession with or addiction to cosmetic surgery (medically necessary surgery, reconstructive surgery and single uses of cosmetic surgery don't usually qualify). "The knife" in this case refers to the scalpels associated with this sort of surgery.

It's sad that so many celebrities today have an addiction to the knife.
