Each country has different slang (modismos)

For Colombia, in Medellin using (gerundio) -ando etc is used plenty.
For example,,, if I am in Centro by junin (parque bolivar, close to the botero statues I would say Estoy juniniando. Or to go,,,voy a juniniar.
callejando -- walking around....when immersed in the culture you will pick up the slang.
