Fresadas is a fascinating word here because it's not a standard dictionary term in this context. While fresa means 'strawberry', fresada can colloquially refer to 'fancy' or 'stuck-up' things or attitudes, often associated with someone trying to act superior or sophisticated.
In the song, the lyric "no salgas con fresadas" (don't come out with fresadas) is a direct plea to someone who has gone to the 'other side' (likely the US) and returned with a changed, perhaps snobbish, attitude. It's a colorful and very Mexican way of saying, "Don't come back here acting all high and mighty or putting on airs." This makes it a unique and culturally rich word to learn.
Get ready for a fun one! Los Dos Carnales and Gerardo Ortiz team up for "Déjate de Cosas," a corrido that's all about staying true to your roots. It kicks off with a direct message to someone who's gone to "el otro lado" [the other side] and gotten rich, but seems to have forgotten where they came from. The singer calls them out, saying, "no digas mentiras no bastando alivianado" [don't lie, you're not that relaxed] and reminds them of the struggles of being undocumented.
It's clear the singer misses the simple life back home, talking about how happy they were with "tres caballos y gallinas" [three horses and chickens]. Now, the person they're singing to is bragging about the "tierra maravilla" [wonderland], but the singer knows they're just "andar de perro de zinc y brindar el cerco" [acting like a tin dog and jumping the fence] if there's no money. They even mention their grandpa asking about their friend and their parents back on the ranch. The song is a blunt reminder to not get too fancy and to remember the family and the life that made them who they are.
