During a question and answer period at Raleigh rally, GOP front-runner Donald Trump was on the receiving end of a question about refugees, celibacy, and "hooking up," that left him virtually speechless.

Trump -- who has a knack for being able to express an opinion on almost any topic regardless of the facts -- found himself flummoxed  before the crowd as the woman posed multiple questions about sex and the refugees.

"I would like to ask one question," the unseen woman began. "Do you think the refugees that are coming here --trying to come here -- that are trying to go to Germany and all over Europe, do you think they are going to become priests and become celibate? If not, what is going to happen to the women in the world in the countries they go into?"

Trump half-grimaced and half-smiled and appeared to mouth "what?" after the woman spoke.

"That's a pretty wild question, say that one more time," Trump replied. "What do you mean?"

"Do you think those refugees, those young strong refugees that are trying to get into America, are going to remain celibate," she replied. "Who are they going to hook up with?"

Trump, who previously had no problem calling Mexican immigrants "rapists," wanted no part in answering the woman's questions.

"Okay, I don't want to get into that question," Trump told the woman as the crowd laughed.
