So it’s obvious that they have done this numerous times before and probably as kids/young adults. Were they in so much danger that their lives were at risk? Or were they just trying to get out some kind of fight where Thor may have boasted too much about his prowess or Loki went and insulted the wrong person? These are the burning questions I have that need answering.

Because all that’s running through my head is them surrounded by enemies trying to figure out an opening to their advantage. Since this was probably pre Mjolnir,  Loki probably whispered something like: “throw something at them!”

And Thor being a good bro likes that idea and can see that working very well. So he just picks up Loki and chucks him at their enemies while Loki screams “NOT ME YOU IDIOT!”
