Kack-Tagesschau is a highly colloquial and humorous compound word. "Kack-" is a prefix derived from "Kacke" (shit/poop), used here as an intensifier to mean "shitty" or "crappy." "Tagesschau" is the name of a very well-known, serious German news program.
In the song, the artist uses this phrase to express extreme disdain and irreverence towards the news, immediately setting a rebellious and comedic tone. It's a memorable and somewhat provocative word choice that stands out.
Get ready for a wild ride with Alligatoah's "Terrorist Im Fernsehen"! This song throws us right into a chaotic scene where the narrator storms a TV studio, fed up with the news. He's demanding the camera on him, declaring, "Kamera auf mich, das ist 'ne Live-Sendung" [Camera on me, this is a live broadcast]. He's got a "terroretische Botschaft" [terroristic message] to share with the entire country.
But here's where it gets hilarious: his big reveal is, "Ich hab den allerkleinsten Penis von der ganzen Welt" [I have the smallest penis in the whole world]! Turns out, someone messed with the teleprompter, leading to an incredibly awkward and funny moment. Despite this epic fail, he's still a "Terrorist for life" who "kämpft immer noch für eine bessere Welt" [still fights for a better world], even if he keeps falling on his face. It's a really funny take on trying to make a statement and things going completely wrong.
