Billy Bullshiner 

Liar; braggart. First use recorded amongst irate residents of 19th century Widnes as an unflattering nickname for infamous French farmer William De Theantandec, who toured North-Western agricultural shows displaying cows with artificially glossed fur.

"13 million? It's 14 million and you know it, you Billy Bullshiner"

Billy bullshitter 

Nickname for someone who lies a lot. Very little they say can be believed, as they are often exaggerating.

You can't believe that Billy Bullshitter - he told me last week he met J-Lo, in a fish and chip shop, in Wigan.
