Tribation 

An act of lesbianism in which one woman and another woman engage in clitoral stimulation by simultaneously rubbing each others' excited clitorises together. This is achieved when one woman lies on her side, lifting her leg up and the other woman spreads her own legs and interlocks herself with her partner in a "scissoring" position. Both women proceed to grind their clitorises together, thus producing sexual stimulation and satisfaction.

I was surprised to see tribation in last night's porno flick since tribation isn't a very common sexual act in porn.

Halo Trial 

A game free for download, played on the computer and intneret by people who either. . .

1. Can't afford actually Halo Combat Evolved . . or

2. Like halo trial's player scene better

Halo Trial's net servers still host many players, as Pro's and noobs run rampant just like any other game. It also could be easier to get noticed by other "pro" players on trial, but it depends on your opinion.

The lead and lag is noticeable larger than Combat evolved.

The campain consists of 1 level and the internet games contain only the Bloodgulch map.

Its endless fun tbh.

ex 2.

Other trial player: NICE!

Trials 

A sport in which sportsmen on modified bicycles attempt to navigate over and across a variety of obstacles, from rocks to cars, using a combination and variation of moves, such as bunny hops, endos and pedal kicks.

The standard Trials bike has is strong, and more importantly light, with sharp brakes, bomb-proof wheels and a low frame with with bars for maximum manouverabilty.

Trials is the only true bike sport, and Trials riders are elite to other sell-out bikers like BMXers and other fags who hang around on the streets these days, getting in our way.

Wow, did you see that guy with the small seat hop over that house?!
