When I looked it up in my dictionary, all I got was 'tension,' when I have first hand knowledge that this definition RARELY is used with this word, in Japanese. Commonly, I see it in テンションが上がる, to express someone is pumped for something, but are there other uses for this word, in the language, that I may not be aware of?

1Does this answer your question? Meaning of 変なテンション– sundownerMay 25 at 3:18
Mostly it's used to describe a mood or atmosphere of excitement or being pumped up as you said.
In a work context it could also describe a atmosphere of intensity and collective focus, such as when a team nears a deadline.
The latter usage sometimes approaches the English meaning of stress and pressure.
Hmm. Could you give me a couple examples of its use in the first context, outside of テンションが上がる? May 25 at 1:21
1I've heard the opposite, テンションが下がった (i.e. the tension went down) This usually has a negative connotation, like excitement being deflated for some reason. For example the family was super-excited about a picnic, but then heard it's going to rain that day.– anroyJun 1 at 6:10
