Niels Bohr and son Aage asked low-level engineer Richard Feynman their questions before asking higher-ups like Oppenheimer, partly to avoid taking up important administrators' time, but also to avoid Kelly's law of committees.

The word 'flag' as pronounced by people with thick Belfast accents. The term is a perfect encapsulation of the disproportionate and overblown reaction to the removal of the Union Jack (as in 'de fleg') from above City Hall in Belfast.

"Wat de fuck like! The taigs got de fleg took down! Let's wreck de fuckin place! No surrender!"
"De fleg has been took down! Before ye know it there'll be a united Ireland! Attack Short Strand! God Save The Queen!"
