does this mean 'happy friday'?

Question

Listo a fiesta'

Answer 1

That's not real Spanish, since fiesta can't be used as a verb. (One of the great things about English is that any verb can be a noun, and any noun can be a verb.)

If you want to ask "Ready to party'," you might say one of the following.

¿Listo (or listos, lista, or listas, depending on your audience) para parrandear?
¿Listo para jaranearte (jaranearnos)?
¿Listo para la parranda?
¿Listo para la pachanga'

Answer 2

Yeah 'Ready to party' or Ready to celebrate' I guess.

Answer 3

I think this means I am ready to party.

I am reminded of the first two line of Shakira's song La Tortura.

No pido que todos los días sean de sol - I am not asking for every day to be sunny
No pido que todos los viernes, sean de fiesta - I am not asking that every Friday be a Party
