Picheando is a fascinating word because it's a Spanglish term derived from the English word "pitching," but in this context, it takes on a different meaning.
While it can literally mean "pitching" in baseball, in Latin American slang, especially in reggaeton, "pichear" often means to ignore, disregard, or blow someone off. Nicky Jam uses it to criticize the other guy for neglecting his partner, singing, "Y ese tipo picheando, trabajó" (And that guy ignoring, he worked) and "Es que ese tipo siempre a ti te está picheando" (That guy is always ignoring you). This dual meaning makes it an interesting and culturally relevant word to learn.
In "Vive Contigo," Nicky Jam sings to a woman who is stuck in a relationship where the love has died out. Her current partner still lives with her, but as the lyrics say, "Ya no te da amor, todo se acabó" (He doesn't give you love anymore, it's all over). The singer sees that her boyfriend is neglectful and doesn't give her the "action or understanding" she deserves.
Nicky Jam positions himself as the passionate and attentive lover she's missing. He makes a bold and direct case for why she should be with him instead, claiming, "El que te hace el amor soy yo" (The one who makes love to you is me). He argues that her boyfriend's time is up and that he is the one who truly knows how to treat her, from giving her warmth when she's cold to understanding what she truly wants.
