Here's the context:

I was heading into work (it's kind of a work/study thing) where this guy I have a crush on (barely know him, he's in my dnd group) was chatting with a bunch of other people. At one point they were joking about weaponizing a project to launch Lawn Darts, to which I chimed in that my parents actually owned some.

At which point he LOOKED ME DEAD IN THE EYE and said "That explains so much".

I have absolutely no clue where the hell that line of thought came from, so I figured I'd ask manifold. If I'm unable to get an answer by the end of the semester (and this market has no "You won't get an answer" response), I'll resolve N/A. Otherwise I'll pick the answer closest to the truth.

I am willing to answer questions in the comments.
