Shwacking 

The act of showering, then masturbating.

After a Delicious Italian Dinner, I think I'm going to have myself a steamy session of Shwacking at home.

favor sharking 

Doing an unasked-for favor for someone, and then using it to try and guilt them into doing something for you.

Sam: "So Bob shows up at my house randomly with some brown bananas and is like 'hey, you can use these to make banana bread,' and I'm like 'uh, ok, I don't really bake but thanks,' and then he invites himself in for an hour and asks to borrow $300."

Joe: "That's some prime favor sharking right there. But my mother in law is worse. She keeps buying us weird vases and knick-knacks we don't need and then calls us ungrateful if we don't spend hours on the phone with her saying thank you and talking about where we'll put them in the house. We keep asking her to stop but she won't.

shaking the can 

From the game "Shake it up" on Mario Party 8 for the Wii, in which a player must shake his/her can for 5 seconds and whoever has the highest stream wins. Naturally, this became a great innuendo for jerking off.

-Where the hell is John?
-Probably shaking the can.
