In Cockney Rhyming Slang, there are a few variations for "taxi," but the most common and widely recognized term is "Joe Baxi." Like most rhyming slang, the term uses a name or phrase that rhymes with the target word; in this case, "Baxi" (a brand of boiler) rhymes with "taxi." Another peer-recommended variation you might hear in the East End of London is "Sherbet Dab," which rhymes with "Cab" (the shortened form of taxicab). A "Sherbet Dab" is a traditional British sweet, and the term has been used for decades to describe a London black cab. For those really deep into the slang, "Andy McNab" (the famous former SAS soldier) is also used for "cab." While these terms are high-value pieces of linguistic heritage, a peer-to-peer "pro" tip for 2026: if you are actually trying to hail a ride in London, just shouting "Taxi!" or using the "Gett" app is far more effective than trying to use rhyming slang, as many modern drivers might not be local East Enders familiar with the "Joe Baxi" tradition.
