Extremely silly, foolish, or stupid; showing a lack of intelligence or good judgment.
From Latin 'asininus' meaning 'of or resembling a donkey,' from 'asinus' (donkey). The word transferred the donkey's reputation for stubbornness and perceived stupidity to human behavior.
Donkeys are actually brilliant problem-solvers, so calling someone 'asinine' reveals humanity's bias: we insult animals for not obeying us immediately, confusing stubbornness with stupidity.
