Donald Trump called into ABC's "The View" on Thursday to discuss -- well, whatever he wanted to talk about, as usual. The topic of his sudden and feisty feud with Ben Carson came up, prompting Trump to explain what had happened.

"He started it," Trump said, referring to Carson, "so remember I like to finish it."

There's a slang term for this: clap back. If you're the type that likes to trust authoritative texts, here are the Urban Dictionary's definitions. In short, it's returning a dis with a dis. Or, in case you would have to also look up "dis," "clap back" means responding to an insult with another, often harsher insult.

Donald Trump is the master of the political clap back. And he's become more and more willing to use it.

We looked at the first back-and-forths between Trump and his 2016 opponents to measure how Trump's ... back ... clapping (?) has evolved over the course of the campaign. They're in order below, with the length of the red bar indicating how long it took for Trump to respond to his opponent's salvo.

Jeb Bush

Bush attacks: Bush first called out Trump in Spanish on June 27, according to a report from a local news site that is no longer online. "Trump spends his life fighting with people, Bush answered in Spanish," the report said. "And he doesn’t, Bush said, represent the values of the Republican Party."

On July 4, a few days, later, Bush went after Trump more directly, saying that he found Trump's comments about immigrants offensive.

Trump replies:

Timeframe: About 8 days

Rick Perry

Perry attacks: On July 2, Rick Perry criticized Trump's comments and lack of experience on immigration.

Trump replies:

Timeframe: Two-and-three-quarter days

Marco Rubio

Rubio attacks:

Trump replies:

Timeframe: Two hours

Lindsey Graham

Graham attacks: Remember this one? Graham called Trump a "jackass" on CNN on July 20, repeating the comment the next morning on CBS.

Trump replies: A few hours after Graham's CBS appearance, Trump offered Graham's phone number to the entire world.

Timeframe: 17 hours

Scott Walker

Walker attacks: Well, it wasn't actually Scott Walker who said anything. There was a Wall Street Journal report on July 24 that a Walker fundraiser had called Trump a "dumbdumb [sic]."

Trump replies: "I can finally attack!" Trump said the next day, and then he did so.

Timeframe: About a day

Carly Fiorina

Fiorina attacks: Fiorina dinged Trump during the "kiddie-table" debate on Aug. 6, but really let him have it on Twitter after Trump's comments about Megyn Kelly.

Trump replies:

Timeframe: About three days

Rand Paul

Paul attacks: Paul also went after Trump during the Aug. 6 debate, but to Trump's face. When Trump said he wouldn't necessarily support the Republican nominee, Paul went after him.

Trump replies: It didn't faze Trump too much. It took a bit for him to reply.

Timeframe: Four days

Ben Carson

Carson attacks: On Wednesday, Carson criticized Trump's faith -- or lack thereof.

Trump replies: On Thursday morning, Trump replied during an interview with CNN.

Timeframe: Half a day

Bobby Jindal

Jindal attacks: Jindal had been trying to get under Trump's skin fairly unsuccessfully for a while. On Thursday, he went after Trump with both bores, calling him a "narcissist."

Trump replies:

Please note: This is not true. When he gave out Graham's phone number, Graham's Real Clear Politics polling average was an even 0.0.

Timeframe: Six hours

But now an important reminder: A clap back isn't necessarily the end of the feud. For example:

We look forward to Trump's imminent response.
