bumser

A situation that turns into total chaos, but in a way that's weirdly funny, ridiculous, or strangely memorable.
Usually involves some kind of unexpected failure, confusion, or accident — but it ends up being a story to laugh about.

"The whole presentation crashed and my mic was on mute. Absolute bumser."

"We missed the train, spilled coffee, and got lost . classic bumser day."

"His code deleted itself... and he laughed. That’s a bumser moment if I’ve ever seen one."
