Green Day singer Billy Joe Armstrong went on an unhinged rant in response to President Trump's 'nuclear button' tweet which ended in him telling all his Trump supporting fans to "f**k off".

Writing on his official Instagram page, Armstrong complained, "This isn't funny. This is our president acting like a madman drunk on power THREATENING to kill innocent starving people by way of nuclear war. The 25th amendment needs to be enforced. This man is sick and unfit for office. I don't care if your liberal or conservative.. this has to stop . Please share #impeachtrump."

Someone probably needs to remind Armstrong that hashtags can't trigger impeachment proceedings.

One of the Green Day frontman's most famous lyrics is, "Do you have the time to listen to me whine?"

If some of the more intelligent replies to his post are anything to go by, it's a resounding no.
