Fipsi 

the art of picking one's klegnuts from one's arsehole.

when one finds oneself without bog-roll having 'rroea'd (diarrhoea'ed) and one must simply twiddle one's thumbs and merrily wait for one's stools to dry, harden, and cling to one's anal whiskers. The waiting period can be anything from half an hour to forty five minutes depending on various factors, including solidity, quantity and patience. Afterward, having found the appropriate tool to extract the unwanted hunks, this act will be known as Fipsiing.

FINSI 

Acronym for 'Fuck It & Sleep In'

You know, the days when you wake up feeling overwhelmed: You have a headache. You've hardly slept because the neighbors were fighting/having sex/getting raided by the cops, you awoke early to the sound of barking dogs and vomiting drunks walking home from the club, You forgot to change your alarm clock for daylight savings and it went off an hour early, at breakfast time there's no toast because the bread is mouldy, no cereal because the milk has turned, no porridge because the rat in the cupboard ate it, and no chance of a McMuffin because you've lost your wallet. You hate your boss, the new departmental manager has been on your back for weeks, the customers are giving you the irrits, you suffer from anxiety from having to deal with the people in Human Resources, and it all just gets a little bit too much....

FINSI!

Fission Mailed

Originated from Metal Gear Solid 2 Sons Of Liberty. What is different is that they changed the first two letters in order to confuse the player. Sometimes used on messageboards to show defeat or total pwnage.

"That sign said Mission Failed so I turned the power off."

"Dude, it was Fission Mailed, they just tried to confuse you, now you gotta start all over again cause you didn't save. Pwned!
