You're obviously old and not jiggy with the latest lingo go buy your coffin already boomer-

Seriously, though, I don't bother trying to figure it out anymore. Every generation invents their own slang to rebel, but I can't tell if this is millenials taking over and injecting their brand, or an attempt to click-bait zoomers, or even gen-x trying to be hip. "Slam" sounds gen-x-ey to me.

It's just shoddy writing, but then I hear a lot of "language evolves," "it's common usage and so correct," and references to fucking Merriam-Webster, the Guiness Book of World Records of dictionaries.
