I am reading a manga and two characters are playing badminton. They take turns hitting the birdie, and each time they hit it, they say「そーれっ」.
This word is actually in the WWWJDIC dictionary, with a definition of "oof; umph; whoosh". There was also a note in the margin of the English transliteration of the manga I found that said it's like a happy grunt.
I am still a little confused. I think I have heard それ (or a variation of it) used as a way of saying, "take that!", like a form of smack talk when doing some kind of move.
How does 「そーれっ」 relate to this? Is it really like a happy grunt, or is it more like smack talk?
