I stumbled on the word ‘tear yet’ in the following sentence in today's Washington Post article titled "Charlie Sheen radio outburst spurs shutdown of ‘Two and a Half men.’" What does ‘tear (yet)’ mean here?

“CBS and Warner Bros. TV have taken the extraordinary step of scrapping production on the country's most popular comedy series, "Two and a Half Men," for the rest of the season after star Charlie Sheen went on his most breathtaking radio tear yet Thursday.”
