Things got tense at a Joe Biden town hall in New Hampshire Sunday, when a Pete Buttigieg supporter asked the former vice president a question and was promptly called a “gibfaced, flapdoodling hornswoggler.”

The young voter, about 25, asked Biden the testy question of why he deserves his vote over Mayor Pete. Biden did not take kindly to such a disrespectful question.

“Why I oughta,” Biden began answering. “You gibfaced, flapdoodling hornswoggler. You better know your onions funny boy. You’re just a dewdropping four flusher taking wooden nickels riding around in your hayburner. I’m giving you the icy mitt.”

Biden’s sick burn was met with a smattering of confused applause. The former vice president has fallen to fourth in most recent New Hampshire polls.
