A video of a man trying to punch an invisible opponent and stacking it outside McDonalds has gone viral.

The early morning footage was posted by Kurtis Bolton on Twitter and shows a man in a yellow hoody take a swing at someone but spins around and falls to the ground. 

Already, over 17million people have watched the fight fail which is captioned: "Got to love Worcester ay."

The tweet has racked up 4,932 comments, 61,600 retweets and 495,000 likes so far. 

In the video, the man the punch was aimed at seems not to notice that the event even happened.

 

The video was taken at 3.36am outside the fast food restaurant where Angel Street and Foregate Street meet. 

It is not clear what led up to the incident - or who else is involved in the fight.

In the comments, Mr Bolton said: "My mate trained his whole life for this."

One of those retweeting the video said: "Guys just won a fight he doesn't even know he has been in."

Another Twitter user said: "Imagine winning a fight you didn't even know you were in." 

Someone else added: "I can't stop laughing."

Another comment said: "The funniest thing is that the guy doesn't even know he's tried to punch him."

Others though pointed out it was lucky the only person he ended up hurting was himself.

One said: "Lucky he missed. One punch is enough to kill/brain damage a person, destroy their family, put your family through hell and send you to prison for manslaughter/gbh."

Another Twitter user added: "Found out an old work bud son (19) was killed with a single punch on a night out.

"The punch floored him and he hit his head on the curb. Never regained consciousness.

"The guys lucky he's not on a man slaughter charge and only ended up with a mild concussion himself.."

Another added: "These people need to learn why punches to the back of the head (rabbit punches) are illegal in boxing. Easily end up on a manslaughter charge behaving like that."
