 That's the term I use when lecturing my boys for making fart noises with their armpits at the dinner table. But it's the most Biden could muster under the circumstances because he knows he's trapped. He can admit his rhetoric for the past decade has been a lie, or he can affirm that Donald Trump is Hitler and therefore it's good to kill him. Biden can't do either of those things because he lacks any kind of moral backbone. So we're left with this middling language. It's not appropriate.
