Подлецам is the dative plural of подлец, meaning 'scoundrel' or 'villain'. It's a strong and somewhat old-fashioned word that isn't heard in everyday conversation as often as more common insults.
In the song, it's used to describe the kind of men who attract good girls: "Очень тянет к подлецам девочек хороших" (Good girls are very drawn to scoundrels). This word highlights the song's central theme of warning against a deceitful lover, making it particularly impactful and memorable.
Ever heard the saying, "good girls love bad boys"? This song is a powerful warning about exactly that kind of romance. The singer is speaking to a girl who has fallen for a man who is handsome and charming, but also dangerous. Everyone can see that his love is a trap (капкан), but she is blinded by her feelings.
The song pleads with her to open her eyes and listen to what people are saying. He's a player who tells every girl he loves her and will only leave her with sadness and sorrow (грусть, печаль). The main message is a desperate cry: "Don't love him, he's bad!" (Не люби, он плохой!). It's a classic story about trying to save a friend from a guaranteed heartbreak.
