It's just a joke about the generic attack name "rocket punch", and what would happen if the punch behaved like an actual rocket launch. This punch went as well as the challenger explosion.
It's a really iconic image, especially to those interested in spaceflight and exploration. Before Challenger, no Shuttle had come apart like this, and it was a real shock to the world. In NASA's words, "The Challenger accident is an important part of our history; a tragic reminder that space exploration is risky and should never be trivialized"
Jesus **** .
"It looks like you've disarmed yourself".
Literally took me less time to think that up than to write it down. If I cared enough to actually think about it, I could probably come up with some better way to frame the "disarm" pun.
But I don't. The point is - your pun game is weak and you should feel like **** .
