Only in Barnsley

When something is so bizarrely weird and awkward, that you scarcasticly use the term "Only in Barnsley", said in a tyke accent, to break the awkward/wtf silence

For instance, " A person that is so clearly hammered/high, that they're dancing round in the middle of the street shirtless" that your response is "only in Barnsley, said in a tyke accent"
