Bring up to in order to get a quick opinion

RUNBY

["Think of casually sharing an idea with someone while passing them, like you might do in a busy office hallway. The phrase suggests a brief, informal check-in."]

"Run by" is a phrasal verb meaning to quickly show or mention something to someone for their immediate feedback. The clue plays on this literal meaning—"bring up" hints at presenting an idea, while "to get a quick opinion" reinforces the casual, speedy nature of the phrase. Think of it like saying, "I’ll run this draft by you real quick"—the answer fits both the definition and the wordplay neatly.
