So I'm a geologist, but this happened a ways back when I was still in school. One of my classes had recently taken a trip to see an outcrop of igneous intrusions in the local hills. I got invited as a plus one to my fiance's cousin and her now-wife's wedding, and as he and I were driving to the venue, I said "oh hey I know this place, there's dikes everywhere around here!"
He looked at me with this shocked expression, and realizing what I just said sounded like, I hastily explained the geologic definition. He made me promise not to speak a word of it at the wedding.
I've seen the two of them at the occasional Thanksgiving in the years since, and though I find humor in it, I've never felt like I could judge if it would be in poor taste to mention the geology beneath their wedding venue.
(Geology fun fact: if you look at the vertical veins of darker rock, notice the gradient spreading out into the lighter rock. That's where the heat of the intrusion literally baked the older rock, and the pink right at the contact is where the silica actually melted into a glassier form.)
Idk but I find this incredibly funny. But also my dad is super into electronics and always tells me whenever he gets a new dyke (diagonal cutter) and I'm just like no you're not allowed to replace me
