fatneck 

verb: to make someone sitting in the back seat uncomfortably cold, by rolling down the front windows of the car. The perpetrator is usually a drunk fat-ass, and an inconsiderate boor, who is not interested in the comfort of fellow passengers. They can be easily identified by their robust neck meat. While the fatnecker is only interested in his own comfort, the person being fatnecked is usually too shy to ask the fatnecker to roll up his window, because the fatnecker is usually an older, burly, high school senior, and the victim, a skinny, waifish, freshman, who will have to earn the respect of his peers before dictating the climate of the vehicle..

"Man, that asshole fatnecked me all the way to Memphis last night. While he was in the front seat, sweating, and being loud and drunk, I was in the back seat, shivering, and too timid to ask him if he could roll up his window."

Fartneken 

The frankly disturbing act of inserting one end of a length of hosepipe up your anus, placing the other end into a drink, then expelling your fart through said pipe. The result is the formation of a methane infused beverage as the gas bubbles through the drink. The drink should then be enthusiastically guzzled by yourself / lover / friend / victim.

See also Stealth - Fartneken where you do this to an unbeknown recipient who will wonder why you are laughing as they down their 'fruity elixir'.

The discipline has also given rise to several sub genres according to odour, volume, bubble volume etc.

'A great meal rounded off superbly when Fatty had to see off 3 Fartnekens after losing at spoof. Turnip with a hint of peanut too. Result.'
