US fast food giant Wendy's has savagely trolled its rival, McDonald's, in a series of hilarious Twitter comments.

It started when McDonald's attempted to schedule a Black Friday tweet but forgot to fully fill in the text.

Its social media team attempted to play it off a few hours later, with a joke about coffee.

But it was too late, as Wendy's had already seen the tweet and went in full trolling mode.

It followed it up by acknowledging its fans.
