“Colgate” CAN mean “hang yourself” in a colloquial form of Spanish, and would be pronounced the same as the toothpaste: “Col GA te,” and does lend itself to making a joke of the product name. Standard Spanish would be “CUEL ga te.” But that word for “hang” means to get hung up or delayed.
What is the brand name of Colgate?
Colgate-Palmolive Company
In 1928, Palmolive-Peet acquired the Colgate Company to create the Colgate-Palmolive-Peet Company. In 1953, Peet was dropped from the name, leaving only Colgate-Palmolive Company, the current name.
