選ぶ
えらぶ · erabu · JLPT N4 · verb-godan
to choose
sounds like eeny-meeny error-boo: pick wrong, get booed, so choose well
erabu sounds a bit like error-boo: choose badly and the crowd boos your error. The kanji 選 is also the sen in 選手 (senshu, a selected player) and 選挙 (senkyo, election), so it always carries the sense of picking one out of many.
