UBF

Unwiped Butt Feeling. One usually gets this feeling after recently defecating. It is an irritating burn / itch around the anus and can also spread to the surrounding cheeks. Anal leakage and poor wiping are the main causes. It can be relieved by wiping with toilet paper in which fecal matter will come off your bum.

Dan: "Man! This UBF is killing me. It hurts to walk."
Dave: "What do you know about UBF. Go to the bathroom and take care of that."

UBF

The union of british fascists (UBF) is a political party often unfairly compared to the BNP. The UBF is dedicated to the purification of the white british living in the UK. This is primarily to solve the overpopulation of the UK, partly to lower very significantly its crime rate, and also to get rid of irritating accents eg easy now i live in the ghetto etc etc.
The founder of the UBF, who tends to prefer to remain unnamed, has no real reason for having these opinions, but there you go.
The UBF has always claimed to be a non violent organization, although the anonymous founder always tends to have UNEXPLAINED bruises on his face and body. I believe him though.
The party's other policies are
Secede from EU
Absolutely no immigration
Kill all chavs
Bring the troops home
Keep takeaway workers
Stop doing what the US tells us

At the next election, i'm going to vote UBF!
Naaaa blud daaan't do daaat!
