adj. — intensifier
expressing annoyance; also used as an intensifier.
Not a Canadianism, see charts. Only the expression "bloody likely" has any significant frequency in Canada. Usage in other Commonwealth countries, especially Australia, New Zealand and Ireland, is much more frequent (see charts).
See also COD-2, s.v. "bloody" (3), which is marked "esp. Cdn, Brit., Austral., & NZ".
