What moments from Wednesday night's Republican presidential candidate debate are you talking about?

Those looking for insights from their peers can look to Twitter. As the three-hour debate came to a close, the social site released its top most-chattered-about exchanges.

Both starred businesswoman Carly Fiorina, who debated with this group of frontrunners for the first time in the presidential race.

Fiorina, when asked to comment on Donald Trump's comments to Rolling Stone about her looks:

"I think women all over this country heard very clearly what Mr. Trump said," she said.

Trump, conceding as Fiorina scowled, responded, "I think she's got a beautiful face, and I think she's a beautiful woman."

Fiorina also dominated conversation with her comments on Planned Parenthood:

"As regards Planned Parenthood, anyone who has watched this videotape, I dare Hillary Clinton, Barack Obama to watch these tapes. Watch a fully formed fetus on the table, it's heart beating, it's legs kicking while someone says we have to keep it alive to harvest its brain.

This is about the character of our nation, and if we will not stand up in and force President Obama to veto this bill, shame on us."
