Pendejadas is a colloquial and somewhat vulgar term that translates to "stupid things" or "bullshit." It's a strong expression of frustration or disbelief.
In the song, Lauri Garcia uses it to convey her exasperation with her partner's lies, singing, "Nose porque me mientes Y me dices pendejadas" (I don't know why you lie to me and tell me stupid things). This word adds a raw, emotional punch to the lyrics, making it memorable and impactful.
Have you ever felt like someone was just stringing you along? Lauri Garcia's "Si Solo Supieras" [If Only You Knew] is all about that frustrating feeling. Our singer is really hurting, seeing old messages and realizing the person they care about doesn't even pay attention to them anymore: "Ya tu ni me pelas" [You don't even pay attention to me anymore].
They dream of a love where the other person would go above and beyond, bringing down a thousand stars and giving everything without being asked. But the reality is harsh. The singer knows they're being lied to, hearing "Me dices que me amas, Me dices que me extranas" [You tell me you love me, You tell me you miss me] while knowing it's all "pendejadas" [bullshit]. The breaking point comes when they see their love happy with someone else: "Te vi con ella estabas Tan feliz que suspirabas" [I saw you with her, you were so happy you were sighing]. It's a blunt, honest song about the pain of being deceived and finally telling someone to just be happy with their new love and stop the "babosadas" [nonsense].
