Levanta esa moral, hombre.

[ROBINDESBOIS]

How can we say to sb, levanta esa moral hombre, apart from, cheer up.
Boost your morale ! BoOst morale !

[Rusty]

Boost your spirits.

I can also give you a pep talk, (unas palabras o una charla para levantar la moral...) (No confundir con una charla motivacional de Pep Guardiola a sus jugadores... eso sería una “Pep’s talk”... ;-)

[Glen]

Chin up, man!

[ROBINDESBOIS]

Nothing like lift your morale

[JPablo]

For that you need a "morale-booster" :-)
