sidetailing 

When a female dog or cat is in heat or attracted to a male they will turn the tail to the side, showing the genitals as a gesture to show they are interested sexually. Men will use this term with other men when they notice a woman checking them out or being slutty.

"Hey man, that chick over there is totally sidetailing"

sidetalking 

1. Using a Nokia N-Gage as a cell phone, thus appearing to hold a sideways taco to one's face.

2. Mimicing the use of a Nokia N-Gage as a cell phone.

3. Holding anything up to your face sideways and talking into it.

I was sidetalking when I held that Super NES up to my face sideways and took a picture of myself talking into it.

Sidewalling

A trail of shit left down the bowl of a toilet.

The Sidewalling game: Capturing a sidewalling with a picture and sending to all your mates. (more points awarded for the tail being close to the top rim. Points deducted for trails leading into the water)

Mike captured a fantastic bit of sidewalling art, After sending a pic to all his mate he received a respectable 9 out of 10.

To look out the corner of your eyes at someone so that they "can't tell your looking"

Performing oral sex by not putting the penis inside the mouth, but rather licking it's whole length from the side.

Getting siderailed (siderailing) by two chick simultaneously - twice the pleasure.
