Avispa literally means "wasp" in Spanish. However, in Mexican slang, it's also used to describe someone who is sharp, alert, and quick-witted.
In the context of this song, the lyrics advise, "hay que andar bien avispa en este medio" (you have to be very alert/sharp in this environment). This highlights the need to be constantly aware and cautious in a risky world, making it an interesting and culturally specific word choice.
Tito Torbellino Jr.'s "El 50" is a really cool look into the life of someone who's worked hard to earn respect and build their way up. The song starts by talking about the effort it takes to achieve something, mentioning "muchas gotas de surco las que ya ha derramado" [many drops of sweat that have already been shed]. It's all about that hustle, especially for those who started from nothing, or "empezar de cero así le vas escalando" [starting from zero, that's how you climb].
He reflects on a time when his neighborhood didn't have much respect for him, but that changed when he got a job offer. That's when the respect started, and things moved "rápido para arriba" [quickly upwards]. He's not super rich or poor, but he's got what he needs, saying "la masa verde me ha dado al alimento" [the green dough has given me food]. He's known as "El 50" now, and that's a name that commands respect. He also gives a shout-out to his parents, saying some of the things he learned from them, and how "con dedicación y esfuerzo andamos mejor que antes" [with dedication and effort, we are doing better than before]. It's a great song about earning your place and staying sharp!
