Ozzy - 2010

Sports provide us with lots of idioms that are used in sports and sometimes in non-sporting situations.
To "call an audible" in American football means to improvise, often in the spur of the moment. The term is based on the practice of changing a play right before the play is run by the quarterback yelling some coded message to the team.
To "hit below the belt" comes to us from boxing. It means to act unfairly or unscrupulously, in disregard of the rules. To hit an opponent below their belt is an illegal move in boxing. Outside the ring, people use it to mean anything said or done that is a "low blow" and unfair.
If someone says that "the gloves are off," they could be borrowing from boxing or hockey. In boxing, fighting without gloves and bare fists is dangerous. Similarly, in ice hockey, when the gloves are off or player "drop the gloves," it means they have engaged in a fight, throwing off their gloves to punch with bare knuckles. This term is used both figuratively and literally. If two businessmen negotiating say "the gloves are off," it means that anything goes and they expect tough negotiations.
Faster Pussycat is an American rock band from Los Angeles, formed in 1985 by vocalist Taime Downe, who remains the only original member.
The original lineup with guitarists Greg Steele and Brent Muscat and bassist Kelly Nickels broke up in 1993. They released four studio albums to date: Faster Pussycat (1987), Wake Me When It's Over (1989), Whipped! (1992) and with a reformed version, The Power and the Glory Hole (2006). In the late 1980s and early 1990s, they sold over two million records worldwide.
Formed during the glam metal and glam punk boom of the 1980s, they took their name from the film Faster, Pussycat! Kill! Kill!. The film is a 1965 American exploitation film directed by Russ Meyer. It follows three go-go dancers who embark on a spree of kidnapping and murder in the California desert. It is known for (as are most Meyers' films) its violence, provocative gender roles, and what one critic called "dialogue to shame Raymond Chandler".It was a commercial and critical failure upon its initial release, but it has since become regarded as an influential "cult" film.
