Bikeshedding
Spending disproportionate time on trivial decisions because they're easy to have opinions about — from Parkinson's example of a committee approving a nuclear plant in minutes but debating the bike shed for hours.
Heard in the wild
“Forty minutes on the button color — pure bikeshedding while the architecture doc went unread.”
Tone check: Technical
Naming it in the meeting (gently) is a public service. Everyone bikesheds; awareness is the only cure.
