Donald Trump is usually the one firing off the insults online but today the tables were turned when the official Twitter account of fast food giant McDonalds told him he had "tiny hands," and was a "disgusting excuse of a President."

In the now deleted tweet, the message also wished for return of the former Democratic President Barack Obama. 

"You really are a disgusting excuse of a president and we would love to have @BarackObama back, also you have tiny hands," the tweet read.

Soon after the tweet was issued, McDonalds claimed to have been "compromised."

"Twitter notified us that our account was compromised," the company said in a tweet. 

"We deleted the tweet, secured our account and are now investigating this," the company said.

McDonalds US spokeswoman Terry Hickey added: "We are now further investigating this."

The President, a fan of both fast food and Twitter, had not responded but is notoriously prone to engaging in disputes on the social media platform.

The tweet was briefly pinned to the top of the McDonald's Twitter account, meaning it would be the first message visitors to the profile read.

The online misfire comes after McDonalds went on a major recruiting drive, boosting the number of digital staff by 200 late last year, according the The Wall Street Journal, a move aimed at winning over millennials.
