I recently came across the phrase うれション, referring to when a dog accidentally
urinates out of excitement. Fairly obviously the first part is derived from
嬉しい, but what else comes together to form うれション?

Its [page on
jLearn.net](https://jlearn.net/dictionary/%E5%AC%89%E3%82%B7%E3%83%A7%E3%83%B3)
and other online dictionaries list しょんべん in a "see also" section, which makes
sense from a definition standpoint, but it's non-obvious to me how the rest of
うれション is derived from しょんべん.

I've also also seen it explained that the ション comes from テンション "tension",
which makes sense and I can see how "tension" could have an implication of
"needing to urinate", but I don't know if this is actually the case and don't
want to blindly trust what I've read on some random forum.

Is anyone able to confirm either of these potential etymologies or explain an
alternative?

**Edit:** This question made a lot more sense in my head, where the prominence
of しょうべん on the jLearn results page for しょんべん made me start reading both as
しょうべん. I failed to notice that they were different even as I put しょんべん into my
question in place of しょうべん.

question
etymology expressions colloquial-language kana
What is うれション a portmanteau of?
Just as the dictionarys say, it's clearly from **うれ** しい and **しょん** べん.
Japanese people like to make four-mora abbreviations like this one. See: [Is
there a generally accepted "rule" for truncating loan
words?](https://japanese.stackexchange.com/q/6718/5010)

At least in Japanese, テンション has no association with urination.
