Is when people take political portmanteaus and then reapply them to new circumstances. "Reaganomics" works because the words glue together naturally, "Bidenomics" still works even if it's uninspired but "Kamalanomics" can't happen. "Joementum", fine, whatever, but please try to come up with something new for other people instead of just sticking "-mentum" on the end of their name. That's the fun of wordplay!!
"Watergate" -> "Whitewatergate" is clever, just sticking "-gate" on the end of things is boring. Etc!!
