Birne literally means "pear" in German. However, in colloquial German, it's also a common slang term for "head" or "brain".
In the song, the line "Männer sind irgendwie weich in der Birne" translates to "Men are somehow soft in the head." This playful and slightly insulting use of Birne makes it an interesting and memorable word, highlighting a common German idiom that might surprise learners.
SDP's "Männer Und Frauen" [Men and Women] is a really fun, tongue-in-cheek look at the differences between, well, men and women! The song playfully points out common stereotypes and observations about each gender, almost like they're from different planets.
For women, the lyrics joke that they're either "zu heiß" [too hot] or "zu kalt" [too cold], always need to use the bathroom, and are scared in the woods. It also pokes fun at the idea that "Frauen haben immer zu wenig Schuhe" [Women always have too few shoes] and are always on a diet but also always hungry. For men, the song says they "verstehen kein Spaß" [don't understand jokes], are "weich in der Birne" [soft in the head], and love sci-fi movies. It even touches on how society measures men by their earnings. Despite all these differences, the song concludes that "Männer und Frauen sind wie Wesen von verschiedenen Planeten / Sie passen nicht zusammen doch ziehen sich an so wie Magneten" [Men and women are like beings from different planets / They don't fit together but attract each other like magnets]. It's a humorous and relatable take on the age-old dynamic between the sexes!
