“This ain’t my first rodeo” (“This is not my first rodeo”)

“This ain’t my first rodeo” means “this isn’t my first time.” It is a similar saying to “I wasn’t born yesterday.”
   
The phrase dates to at least the movie Mommie Dearest (1981), the Joan Crawford biopic, where she is credited with saying, “Don’t fuck with me fellas. This ain’t my first time at the rodeo.” Vern Gosdin released the song “This Ain’t My First Rodeo” in 1990.
 
“I didn’t realize I was supposed to know how to do everything by my second rodeo” and “People never tell you when it’s their first rodeo, but are eager to inform you when it’s not” and “Wish I paid more attention during my first rodeo” are related sayings.
 
[This phrase was discussed on the American Dialect Society listserv (ADS-L) in September 2011; some of the following citations were found by Bill Mullins, Jesse Sheidlower and Garson O’Toole.]

21 July 1999, New York Times, “Clemens Is Looking For His Keys” by Harvey Araton, pg. D1:
Clemens is 36, a certain Hall of Famer who teaches us again that there is apparently no immunity to the misplacement of belief. Back in Boston and again in Toronto, the Texan had already gone through the process of reinventing himself. Whatever he’s really thinking about his power pitching, he’s publicly playing it cowboy cool.
 
“This is not my first rodeo,” he said. “I’ve been down the road.”
