bite someone's head off

Also, snap someone's head off. Scold or speak very angrily to someone, as in Ask her to step down from the board? She'd bite my head off! The first expression, dating from the mid-1900s, replaced the much earlier bite someone's nose off (16th century); the variant was first recorded in 1886.
