When someone sticks their thumb backwards in your butthole and they fart on your thumb...thus the thunder sound.

1) "... It's a privilege to have people listen to your views, and if people get them arse backwards sometimes, that's the price you have to pay ..." -- Alexei Sayle, comedian, satirist and Young Ones co-star, after apparently dissing his home city.
2) Bill: I put my trousers on arse-backwards today.
Ben: Well done. That's correct.

The act of pooping on a toilet backwards, as if straddling the toilet. In most cases the trousers and undergarments must be completely removed before engaging in this act.

Thise maybe tough to understand but help me out here. Backwards racism is when a race (usually white people) is shown no "special" treatment. As in they are considered basic and therefore have no heritage etc... Don't believe me? Think about this:ever see any sort of heritage events for white people? Ever see any sort of special clubs at school for white people? If you try to start a club and they ask what you are, white won't be an answer. White is considered the basic and therefore deserves nothing extra. Another thing, if a white person says something like nigger or even black guy, he's racist, yet white boy is as bad as those two, considered normal. White people are a race and should be treated like one.
White people are to race as white is to color:how many times have you heard someone say:white isn't a color?

You need a mangina. This is basically an inverted dick, like a vag, but with no uterus or any of that shit. First, you reach into your ass and pull on your prostate gland, which, pulled with enough force, will cause your cock to come out of your ass. Then, you do a guy in the ass--from the ass.
