2-A Welsh version of Jackass but funnier. Contains such Gems as- Arse grip tape slaloms, Running over dation with a car, Is this Ice cold? and it sequel OH MY FUCKING GOD THAT ICE IS COLD! and Slaps (A game involving Well, Slapping). Some Banned senes involving Piss and shit eating, Giving himself a knob Piercing and running into a Bull. Shockingly, the bull wins. Also One seen called ‘Beer Enema’ Where one guy gets a Enema with beer and another drinks it. This has to be seen to be believed… Only On MTV UK (I think)

Ok, this is the official way to give a dirty sanchez people, get it straight. First you must be doing a girl doggy-style, then you stick a finger in her asshole, and reach around to administer the poo-stache.
I told the bitch I'd give her a Dirty Sanchez if she wouldnt shut her trap.
