Pichear is a popular slang term in the Caribbean, especially in reggaeton music. It's a fantastic word for English speakers to learn because it's derived from the English word "to pitch," as in baseball.
Just like a pitcher throws a ball, when you "picheas" someone, you are ignoring them, brushing them off, or "curving" them. In "Toda," the artist says, "Quédate conmigo y le picheo a todas" (Stay with me and I'll ignore all the other girls), using this cool slang to promise his undivided attention.
This song is one giant, very convincing argument for a woman to leave her boyfriend. Each artist takes a turn explaining why they're the better choice, and they don't hold back! The main point is that her current man is lazy and doesn't appreciate her. As Alex Rose puts it, "Él te lo hace a medias, yo te beso toda" (He does things halfway, I kiss you all over). The singers promise a much more intense and complete passion.
They describe a secret relationship that's been going on for a while, full of late-night calls and sneaking around. They know it's wrong, but the connection is too strong. Rauw Alejandro even says, "Además del sexo, mami, quiero amarte toda" (Besides sex, mommy, I want to love all of you), suggesting it's more than just physical. Cazzu's verse gives the woman's perspective, admitting she'll drop any plans with her boyfriend if this other guy calls. It's a super direct and steamy track about choosing a wild, all-consuming love over a boring, unsatisfying one.
