It was the clap back heard around Twitter. With just three little words, presumptive Democratic presidential nominee Hillary Clinton was able to shut down Donald Trump.

It all started when Barack Obama publicly endorsed Hillary Clinton in a web video on Thursday.

"I want those of you who have been with me since the beginning of this incredible journey to be the first to know that I'm with her," Obama said. "I am fired up. And I can't wait to get out there and campaign with Hillary."

Of course the presumptive Republican candidate Donald Trump responded using the platform we have become accustomed to hearing the obnoxious billionaire rant on: Twitter.

"Obama just endorsed Crooked Hillary," Trump wrote in a tweet on Thursday afternoon. "He wants four more years of Obama — but nobody else does!"

While Ms. Clinton could have just held her head high and continued to bask her recent campaign success and major endorsement and not pay mind to the haters, she led by example to show that no one should tolerate online bullying and tweeted back.

And with a comeback three words long, Clinton was able to give it to Trump.

"Delete your account."

That was it, the Twitterverse went wild. That's because there is a lot more meaning behind this phrase than meets the eye. Twitter users know that the phrase is commonly used on the platform as a way to diss someone. It's pretty much saying your point is so bad you should no longer be allowed to tweet.

Clinton's Trump tweet was retweeted more than 310,000 times and liked over 360,00 times, with #deleteyouraccount becoming a trending hashtag and has generated more than 71,000 tweets with various memes.

It became all anyone could talk about on the internet, but Trump wasn't going to sit back and let her get the last word.

"How long did it take your staff of 823 people to think that up-and where are your 33,000 emails that you deleted," he responded.

Ooh, burn. Trump kind of has a point here because usually Clinton signs her name at the end of her tweets to authorize them. Since this tweet wasn't signed "-Hillary," it was most likely her staff who runs her Twitter account that wrote it.

Even still, it doesn't take away from the fact that Trump got owned. But of course his fellow Republicans weren't going to sit back and let him get virtually humiliated. Republican National Committee Chairman Reince Priebus was one of the few who came to his defense, chiming in to Clinton "If anyone knows how to use a delete key, it's you."

Hillary did not make additional comments, except for posting a quote from Senator Elizabeth Warren that reads, "Trump 'doesn't care who gets hurt as long as he makes a profit off it. That cannot be the person who leads the United States.'"

It seems like this is only the beginning of a Twitter war between the two. Check out the tweets below.
