To avoid sleeping for a long period of time and keep going in style - usually with some chemical assistance.

Or, to make a quick stop by a friend's abode to procure said chemicals.
1) "Welcome! Are you guys gonna hang out for a bit?"

"Oh no, we're just playing through. Are Tina or Charlie here at the moment?"

"No, but Molly is in the back. You want to meet her?"

"Sure! Bring her out."

2) "Mind if we play through?"

When a friend is hooking up with someone in the room, and then a couple of his (or, less frequently, her) buddies will come into the room naked, aside from a golf club & ball, and perhaps a swanky hat.

The two mid-coitus lovebirds will likely object, at which point those golfing are obliged to inform them: "Oh, don't mind us, we're just playing through."

Done more for comedic effect than any sort of malice. Negative effects to friendship can be mended with naked apology.
1.(Bobby hears Dee and Martin in the room hooking up, and immediately drops trou.)

Bobby's friend: Dude, what are you doing? Put your dick away.
Bobby: No can do. They're holding up play.
Bobby's friend: Christ, I'll go grab the putter.

2. Dee: What the FUCK?! Why are you guys here? And why are you naked? Get out!
Players: (In British Accent, audible whisper) Oh my. It seems the pitch is slightly elevated here, but he's judged it beautifully... magnificent shot.
Dee: Martin, say something!
Martin: It's fine, they're just playing through. And look at that stroke. So elegant (gives Bobby high-five).

A phrase borrowed from the golf course. This gives permission to an individual or group to discontinue listening to your boring discourse about yourself.
Will: ...and I won "Best Lawyer" award again, and I have 704 friends on Facebook, and I've never suffered, and once at the Eiffel Tower..... (then notices the attention of listener is wandering) ...oh, that's just go ahead and play through....and I took her picture at the catacombs...and I'm handsome...

When a male is having sex with a female and his buddy comes along. The male in mid coitus will stop before he is done and let his buddy have sex with the female. After his buddy is done the original male will continue. Usually happens in a train.

the act of throwing a frisbee into a room where two (or more) people are fornicating, then following the frisbee into the room completely naked, saying "I have to play it through." Then grab the frisbee, and run out.
I tried playing it through on Conner and Lauren, but he chased me with a bat afterwards.
