But unfortunately for pickle lovers the McPickle burger was only created for an April Fool's Day prank.

While some social media users cottoned onto the April Fool's Day prank straight away, others were outraged the burger wasn't actually available to buy.

'If only it wasn't April Fools,' one person wrote.

'Don't play with me McDonalds... make this happen,' a second implored.

'Omfg if this is April Fools' joke [I'm going to] be mad,' another added.

But others couldn't stomach the idea of a burger filled with pickles.

'Even though it's an [April Fools], this is still disgusting to even think about,' said one.

A second disgusted user wrote: 'Just vomited at the [sight] of it'.

Another person offered some advice on how someone could create their own McPickle burger.

'If you really, really want one just buy a cheeseburger and ask for a billion extra pickles,' they commented.
