Batear

Batear literally means "to bat". In Mexico City it is used to mean "to reject with utmost emphasis." Picture the person you're asking something from as a slugger at bat: your demands or suggestions can be sent out of the ballpark in a violent fashion with a big swing. The use of batear is usually accompanied by the gesture of batting a baseball to the centerfield and contemplating it as it goes beyond the fence.

Dar bat (lit. give bat) can be used in lieu of batear.

Example 1:

Hernán: ¿Te van a dar vaciones en semana santa?

Cuauhtémoc: Le dije a mi patrón pero me bateó horriblemente.

Hernán: Are you gonna have a spring break?
Cuauhtémoc: I asked my boss but he sent me back in a horrible way.

Example 2:

Mamá: Con las mujeres debe ser persistente, mijo. A tu papi lo bateé varias veces, pero siguió insistiendo, y al final le dí lo que quería.

Hijo: ¿Podemos cambiar de tema?

Mother: With women you have to persevere, my son. I rejected your daddy over and over, but he persevered and in the end I gave him what he wanted.
Son: Can we change the subject?
