Hängetitten is a very colloquial and somewhat crude German term that literally translates to "hanging breasts" or "sagging breasts". It's a provocative and memorable word due to its directness and the imagery it evokes.
In the context of the song, Sido uses this term in a derogatory way towards Sarah, saying, "Ich find' die Hängetitten eklig, man" (I find the sagging breasts disgusting, man). This line is part of his aggressive and insulting tirade, making it a striking and somewhat shocking word choice that stands out in the lyrics.
Sido's "Sarah" is a wild ride! He starts by saying he needs to tell Sarah something, but since she doesn't like hip-hop, he'll sing it for her. He immediately asks, "Warum bist du so gemein zu mir? Warum können wir keine Freunde sein?" [Why are you so mean to me? Why can't we be friends?]. It feels like he's trying to win her over, even saying, "Du liebst mich doch, los, zeig es mir" [You love me, come on, show me].
But then things take a sharp turn! He looks at her Playboy photos daily but thinks she's not getting prettier, even finding her "Hängetitten eklig, man" [sagging breasts disgusting, man]. Ouch! He warns her not to overdo her jokes, because what he's about to say is her own fault. And what he says is... well, it's blunt: "Du bist eine Hure. Du Nutte bist 'ne Hure" [You are a whore. You slut are a whore]. He admits he's a "Prolet" [prole] and calls her a "Stück Scheiße" [piece of shit]. He even says, "Dabei bist du's doch gar nicht wert" [But you're not even worth it]. It's a really intense mix of hurt, anger, and insult, with him even questioning why he's getting so worked up, then deciding, "Scheiß' drauf! scheiß drauf" [Fuck it! fuck it], only to change his mind and keep the insults coming. It's definitely a memorable song!
