hand it to

(slang) To harm or kill (someone).

(slang) To try to impress (someone) with deceptions.

Old British underworld and criminal slang meaning to harm or kill someone — to deliver violence as casually as handing something over. The euphemistic framing is darkly ironic; handing something out sounds almost generous, which makes the violent meaning hit harder. Like many criminal slang terms, it was designed to be understood in-group while sounding innocuous to outsiders.

(dated, colloquial, US, AAVE, mostly, sarcastic) Used to dismiss another person's argument by indicating that one is not prepared to hear or read anything further from that person. It is often used while simultaneously holding up the hand with the palm facing the speaker.
