Cariñitos is the diminutive of cariños, which means 'affections' or 'caresses'. The diminutive ending '-itos' adds a sense of tenderness and endearment, making it 'little caresses' or 'sweet nothings'.
In the song, the singer describes how someone entered their heart "Con mentiras y cariñitos" (With lies and sweet nothings). This word beautifully captures the deceptive yet tender ways someone can win affection, making it a poignant and memorable choice.
Have you ever fallen for someone slowly, almost without realizing it, only to find yourself completely hooked? That's exactly what Pedro Infante sings about in "Despacito, Muy Despacito" [Slowly, Very Slowly]. He describes how this person "Se fue metiendo en mi corazón" [went getting into my heart] with a mix of "mentiras y cariñitos" [lies and little affections]. He knew she wasn't good for him, but his passion grew "despacito, muy despacito" [slowly, very slowly], and he gave her everything, "sin condición" [without condition].
Now, he's in a tough spot because he wants to stop loving her, but "No responden las fuerzas de mi alma" [The forces of my soul don't respond]. He can't forget her, even though the happiness they shared is gone, leaving only memories. It's a classic tale of falling hard and fast, even when you know better, and then struggling to break free from that powerful connection.
