Dear La Wyo, as Pedro says, UN ABRAZO is A HUG. Variations are:
UN GRAN ABRAZO = A BIG (BEAR) HUG
UN ABRAZO DE HERMANO = A BROTHER'S HUG
UN ABRAZO LIBERTARIO = (oops - truly anarchist, but so emotional)
UN ABRAZO DE LOS OTROS = (mmh.. no, doesn't have a translation) :))
See you in the CANTINA ! - Yours, Andrés
