¡tenga paz! Stay Calm!

My new Tico T-shirt (la camiseta)
It has a local slang expression to ask another person to “stay calm.”

For locals, I got this at Arteria, a little shop with many items using local slang, located on 1st Avenue in San Jose, across from Tribunal Supremo de Elecciones.  (The link tells of other locations.)

I will wear it to my Su Espacio Lingua Fiesta tonight.  🙂

LITERAL TRANSLATION?
SpanishDict.com & GoogleTranslate both say:  “have peace”
