Voseo is the use of the second person singular pronoun vos instead of tú. Vos is used extensively as the primary spoken form of the second-person singular predominantly in Argentina, Uruguay, Paraguay, and in the Central American countries of Guatemala, Honduras, El Salvador, Nicaragua and Costa Rica.

Here are some examples of Rioplatense Spanish and European Spanish in the imperative form, the first form is Rioplatense Spanish and the other is European Spanish.

The song “Cha Cha Cha”, by La Mosca, has some examples of voseo, have a look:
