Parents in the Mexican state of Sonora will no longer be allowed to name their children Facebook, 'Rambo"or 59 other now banned given names.
The names have been found at least once in state registries and the list could grow because officials are still checking in the state's 132 registries of babies, Sonora state civil registry director Cristina Ramirez said.
The law banning a list of 61 odd or offensive names seeks to protect children from being bullied, Ms Ramirez said.
"The law is very clear because it prohibits giving children names that are derogatory or that don't have any meaning and that can lead to bullying," she said.
Ms Ramirez said that in the town of Navojoa a boy was recently named Juan Calzon, or Juan Panties, and a girl was named Lady Di.
Other odd names include a girl called Marciana, which translates as Martian, and a boy called Circuncision, or Circumcision.
Sonora is across the border from the US state of Arizona.
