Ficticia translates to "fictitious" or "fake." It's an interesting word because it's not as common as other synonyms, making it stand out.
In the song, the artist uses it to describe a woman's story about being single: "Dice que es soltera, pero sé que esa historia es ficticia." This reveals a deeper layer of deception and adds intrigue to the narrative, suggesting that things are not as they seem.
In "Me Quieres Mentir," which translates to "You Want to Lie to Me," Miky Woodz tells the story of a complicated and toxic relationship. He sings from the perspective of an "OG," an experienced man who sees right through the lies of a woman from his past. She only contacts him when it's convenient for her, usually after she's had a few drinks or fought with her current partner. He knows her true motives, singing, "You look for me because they were unfaithful to you / Or that bastard doesn't satisfy you."
The singer is caught in a difficult position. He knows she's using him and lying about being single, but he also admits she has a powerful, almost addictive hold on him. She "knows the way to make me fall" and uses her power to wrap him up in her drama. Despite their intense physical connection, he's grown tired of the game. He declares, "We only hook up when it's convenient for you / But I'm retiring from the game / This isn't entertaining anymore," showing his desire to finally break free from this manipulative cycle.
