Slippin' Jimmy is the nickname Jimmy McGill earned long before he became Saul Goodman in the Breaking Bad universe. In Better Call Saul it refers to his younger years in Cicero running small slip and fall scams and other street cons. The phrase stuck with fans because it sums up the character in two words: charming, reckless and always working an angle. Short clips of the line later circulated on soundboards and in edits as a shorthand reaction whenever someone online looks like they are running a familiar trick.
