Waterbedding

When you are fucking a fat girl from behind, and as your pelvis smacks against her ass, ripples extend all the way up her back much in the fashion that a waterbed ripples end-to-end when you only step on one side.

1: Did you see that girl I was grinding with at the club last night?
2: Yeah, but she was kinda fat, dude.
1: I was just gonna say, I could feel some waterbedding just when we were dancing so I bet it would be out of control if I took her home.
2: So what did you do instead?
1: .....itookherhome , D: D: D:

Waterbending 

A special ability given to the people of the Water Tribes in the TV show Avatar: The Last Airbender. The skill of waterbending gives a person the ability to control water and various forms of (ice, snow, steam, etc.). One variation of waterbending is Bloodbending, developed by Hama, a survivor of the Fire Nation Raids on the Southern Water Tribe. A Waterbending Master can skillfully bend anything with water inside. People have been shown controlling plants by bending the water inside; bending perfume (which presumably had water in it), water mixed with earth, mud (which raises some questions), and stew to name a few. In episode 8 of Season 3 "The Puppetmaster" we learned that a skilled waterbender can actually pull the water from the air or from plants. Waterbenders can also freeze or unfreeze water. The style of waterbending mirrors that of Tai Chi in both its movements and the way that waterbenders turn their defense into their offense. There are three known styles of waterbending: Northern, Southern, and Foggy Swamp Style.
The origins of waterbending are said to have come from early Water Tribe members watching as the moon pushed and pulled the water, and they learned to do it themselves.
Some waterbenders posses the healing abilities of water. The healers use the water to relieve sickness by redirecting the chi paths in the human body, however, using waterbending to heal will not heal everything.
Waterbenders draw their strength from the moon, therefore, their abilities are at their peak at night and during and especially during a full moon. They are at their most vulnerable during a lunar eclipse when waterbending is rendered impossible.

Katara is a waterbending master and learned from Master Pakku.
Thanks Wikipedia for all the info!

Water Bedding

An extremely large bellied woman is laying spread eagle on your bed and while you are eating her out she lifts her belly up and drops it on your head. Effectively recreating the ripple of a water bed in her belly fat.

Beatrice water bedded me while I was performing fellatio on her vaginal region. She was water bedding me because I am a naughty boy.

waterbirding 

Leaning up and down repeatedly to kiss your partner, normally to annoy them, like a toy bird dipping down to drink water

Babe, you're waterbirding again.
