"Blot one's copy book" is an idiom that is often used in British English. It refers to tarnishing one's own reputation or doing something that brings disgrace, especially in a professional or academic setting. The phrase "blot one's copy book" originated from the practice of handwriting, where blotting ink on a copy book would ruin the neatness and credibility of the work.

"One's name is mud" is another idiom that conveys a sense of disgrace or infamy. This idiom suggests that a person's reputation has been severely damaged, to the point where their name is associated with disrepute or shame. The origin of this phrase is debated, but one theory suggests it comes from the historical figure Doctor Mudd, who set the broken leg of John Wilkes Booth, the assassin of President Abraham Lincoln. As a result, Mudd's name became synonymous with disgrace and infamy.
