Pichea is a popular Puerto Rican slang word derived from the English baseball term 'to pitch', which has evolved to mean 'to ignore' or 'to let something go'.
In the song, Bad Bunny begs his partner to just give him a kiss and "pichea que tenemos que hablar" (ignore that we have to talk). Mastering Caribbean slang like this is the absolute best way to finally understand the lyrics of your favorite reggaeton artists!
Everyone dreads reading those four words on their phone screen: "tenemos que hablar" [we need to talk]. In this track, Puerto Rican artist Bad Bunny goes into full panic mode, immediately scrambling to remember what trouble he got into the night before. His mind races through every possibility—did someone catch him flirting, did he hook up with someone ("¿a quién ahora me tiré?" [who did I sleep with now?]), or did he just look at the wrong person at the club? He starts off claiming he is completely innocent ("yo soy un angelito" [I'm an angel]), but within seconds his defense crumbles as he suddenly remembers kissing someone while partying, before trying to play dumb with "ma', yo ni me acuerdo" [babe, I don't even remember].
What makes the song so hilarious is how desperately he tries to deflect the blame instead of facing the conversation. He blames gossip from her friend and her cousin Omar, and then begs her to just ignore the whole issue ("pichea" is classic Puerto Rican slang meaning "ignore it" or "let it go"). The absolute peak of his panic hits at the end when he realizes she already complained to his own mother, and now his mom has sent him the exact same terrifying text: we need to talk.
