My whole family uses 'upandcomeance' for people who should get what they're deserving (negative)! This comes from my brother, who initially eggcorned 'up-and-comer' with 'comeuppance,' and we all just kept it. 😆
We use “like a banshee” as a phrase to indicate an extreme level of whatever-it-is. “Scream like a banshee” is the original; we say “hurt like a banshee,” “snored like a banshee,” “ran like a banshee…”
Family vernacular is the best.
When we're telling a story in ours, it's normal for there to a place where someone says "and then, the ensuement." This means "and then it all went wrong", which evolved from our overuse of the phrase "chaos is ensuing" when The Kid was little.
