Gammon is a term best used to describe white liberal
men who spend most of their days ranting angrily on Twitter about people slightly right of them or about people who voted for Brexit.
Takes its name from the pork product that is pinkish-red and
salty which perfectly describes the faces of these
men.
Gammon
will often use the term against people who voted for Brexit, often accusing leavers of being racists and xenophobes, meanwhile they march in Labour rallies that are majority white and middle aged while supporting Corbyn, a red faced old white antisemite.
Recognising irony clearly isn't in a Gammon's nature.
Many no doubt
will still seek to replace this
definition about how it doesn't apply to them, unable to recognise that they are similar to those that they dislike so much.
