I see this written a lot in advertising and amongst younger speakers - often as a standalone sentence referring to an act, product or activity. Can someone shed some light on how it's used and what exactly it means? To me it seems almost contradictory, but I guess I'm coming at it too literally.
means as much as that this is inappropriate and pointless, but still nice/awesome ("geil").
The expression ("leider geil") became famous through a song by Deichkind "Leider geil"
- turn on subtitles in English to understand better
This music video shows various incidents that are "leider geil". Watch the video, then you know more!
"Autos machen die Umwelt kaputt, doch ein schönes neues Auto ist leider geil"
...that means something like a new car would be very cool ("geil"), but since it harms the environment (CO₂), the word "unfortunately" is used, hence "leider geil". So it's a contradicting statement.
