Bichería is a colloquial and somewhat vulgar term, often used in the Caribbean, that refers to nasty things, trash talk, or even gossip and malicious comments.
In the context of the song, the line "Siempre que lo saco me mira mal, sale con bichería'" suggests that when the singer brings up a certain topic or person, the woman reacts negatively, perhaps with insults or unpleasant remarks. It's an interesting word because it's not commonly found in standard Spanish dictionaries and carries a strong, informal connotation.
In "LOKITA," Mora tells the story of a passionate and spontaneous encounter from a man's point of view. The narrator playfully insists that he's not to blame for what happened, singing, "Te juro que yo no hice nada, fue ella solita" (I swear I didn't do anything, it was all her). He claims the woman goes "loquita" (crazy) for him and that after a few drinks, things escalated naturally until they were "taking off our clothes."
The lyrics suggest this isn't just a physical connection. The narrator mentions that the woman was in a previous relationship where she felt neglected, and he is the one who gives her the attention she craves. He describes her as his "loca mía" (my crazy girl), suggesting a possessive but affectionate bond. He sees himself as the one who understands her and comforts her when she arrives feeling sad or "empty."
