3-way phone call attack

When two people call one person but the third person doesnt know the second person is on the phone.

Zoe and Liz call Liz's ex-boyfriend but he doesn't know and get information about the breakup.

"Did you hear about how she "3-way phone call attack" me?"

3 way handshake

When three men stand in a circle and jerk off the gentleman to their right.

Why does it take 3 networking guys to install a switch? These guys are so lazy. With all three of them in the network closet like that, I'll bet they are giving each other a 3 way handshake.

The 3-way swivel 

A variation of the Spit Roast. Whilst one person is servicing 2 partners from both ends, the partners then, in sync with each other, spin the servicing member without removing themselves from said member. Best done when the fishing is slow on a boat, preferably with a woman under 110lbs.

Thank God we had Cindy on board. The fishing sucked but we were able to rig up The 3-way swivel. She got sea sick afterwards but it doesn’t matter because we got ours.

3-way knuck

When you and 2 of your buddies celebrate a good game of darts, and you do a “3-way knuck”. A fist bump between 3. A rare simultaneous connection of knuckles felt between each individual.

After our game of countdown, we did a 3-way knuck to celebrate the game.
