A "bullshiner" is a cleaner version of "bullshitter". It waqs made mainstream by favourite Big Brother housemate, Mario Marconi.
The word is often part of the expression "Billy Bullshiner", There are many theories as to why
Mario puts the word/Name "Billy" at the begging,
one theory is that, because it'
s alliteration it makes it sound good and rolls of the tongue. Another is that the name "Billy" often crops up before other
famous derogatory slurs, such as "Billy no Mates".
