Banana for Scale
Internet-native reference for informal measurement. In corporate use: any rough benchmark offered when precision isn't available. The banana is metaphorical; the imprecision is not.
Heard in the wild
“No hard numbers yet — this estimate is banana-for-scale quality.”
Tone check: Cliché
Signals honest imprecision, which beats dishonest precision. Know your audience before deploying memes in meetings.
