We now know what the next five months of Hillary Clinton and Donald Trump battling for the U.S. presidency will look like: It should be a twitter war like the craziest celebrity rivalries that have kept Hollywood tabloids busy. Even the Amber Rose versus Kylie Kardashian has nothing on the presumptive Republican and Democratic nominees when it comes to trading fast insults in 140 characters.

Thursday's social media spat started soon after President Obama endorsed Clinton. Trump immediately tweeted his insult of "Crooked Hillary."

Obama just endorsed Crooked Hillary. He wants four more years of Obama--but nobody else does!

Clinton (or a staffer with her password) responded with a message that became a hastag #DeleteYourAccount.

Delete your account. https://t.co/Oa92sncRQY

This gave Trump an opening, considering the controversy (and FBI probe) of Clinton's missing State Department emails.

How long did it take your staff of 823 people to think that up--and where are your 33,000 emails that you deleted? https://t.co/gECLNtQizQ

Republican National Committee (RNC) Chairman Reince Priebus added hit two cents:

.@HillaryClinton If anyone knows how to use a delete key, it's you.

Five months to go! Stay tuned.

Lead Stories has uncovered evidence of a historical precedence for such. Abe Lincoln and Stephen Douglas engaged in a similar social media spat in 1860. (Just kidding.)

It's official, this will go down in Twitter Meme history. #DeleteYourAccount pic.twitter.com/2RVa72dsQv
