bright spark
Someone quite sharp
A bright spark is someone clever or quick-witted, but the phrase is more often used sarcastically to mean the opposite—someone who has done something foolish: Which bright spark left the door open?
The sarcastic use dominates in British English, where it functions as mild mockery rather than genuine insult.
