Joe Biden: Where's my 'old butt buddy'? Vice president gives shout-out to friend in Iowa speech

You just never know what will come out of Joe Biden's mouth.

Speaking in Iowa on Thursday, the vice president called out from the podium:

"And Neil Smith, an old butt buddy, are you here Neil?" Biden said. "Neil, I miss you, man. I miss you."

"Butt buddy" has several meanings, including "close friend," according to the Urban Dictionary.

But it could be that Biden was just stuttering rather than saying "butt." As a child, he had a stuttering problem.

In any case the vice president did not correct himself.
