I have always loved magic/mages/wizards/locks/witches/shamans in video games. When you have to make tons of alt accounts on MMOs or RPGs everytime i did another mage playthrough I started coming up with names for the memes. Some were okay, some were bad.
When I went to do a hardcore playthrough of a game and was trying to think of a “sweaty” (sweaty being someone who puts in a lot of effort, for those unaware) pun, sweatyfireballs was born. I was so proud of if it, it became my new go to user name over my long running previous name that I came up with for my mage on vanilla wow. I peaked that day.
I always assumed the reason they repeated that line and only implied it was for headaches with the animation is because they knew it wouldn’t work and wanted to avoid being called out for false advertising. Honestly if I was ever told it worked I would be absolutely astounded.
