Could also be used as "Octopi War" depending on the level of intensity. Octopus fight is when you get that over excited feeling in your stomach like there are octopi tangled up in it and the only way to express how you feel is with a hand gesture (looks like your hands are fighting). Definitely a good thing.
Octopus fight, the act of feeling overly excited and squirmy.
"I dont know about you Cass, but I feel as if a massive Octopi War has erupted in my tummy"
