Explain xkcd: It's 'cause you're dumb.
Reverse Polish notation is a method of writing mathematical expressions, where operators are after their operands, not between. For example, 2 + 2 becomes 2 2 +, and (2 × 2) / 3 becomes 2 2 * 3 /. This comic plays on that, by placing a Polish Sausage (a North American term for Kielbasa) after both halves of the bun instead of between.
The title text is a pun on the fact that Reverse Polish Notation is also known as Postfix notation. "Fixins" is a Southern US slang for condiments such as mustard, chopped onions, and more.

- [A sausage is sitting to the right of an empty bun.]
- Reverse Polish Sausage
I know exactly what RPN is but I have no idea what a Polish Sausage is, nor what the "postfixins" joke is about (is a fixin a thing? I've never heard of them). If someone could explain these presumably American terms I'd appreciate it. 18.104.22.168 14:34, 17 September 2013 (UTC)
- Read the explanation, everything is there.--Dgbrt (talk) 15:45, 17 September 2013 (UTC)
- No it isn't. Anon, the US refers to Kielbasa as Polish Sausage, and "fixins" are condiments such as mustard and chopped onions. I'll update the explanation. Yomikoma (talk) 17:55, 17 September 2013 (UTC)
- I didn't know that. Thanks for your help. Further investigations at urbandictionary gave me this: "A Southern (USA) word for the supplemental food...". It does belong only to the south of the US.--Dgbrt (talk) 19:13, 17 September 2013 (UTC)
