Bückstabü 

A word, probably made up by Rammstein, which is commonly referred to as meaningless, but in an interview Rammstein stated that it's a synonym for lust and uncontrolled sexual desire. It could also be an abbreviation for "Bücken statt büffeln" (bending down instead of studying)

Till Lindemann screams the word Bückstabü in the Rammstein song "B********", which is tackles the topic of rape.

Bückstabü 

A word made up by the German metal band Rammstein. They've never given a proper explanation of what it means, but its probably made of the two words Bück (=bend over) and Stab (=rod). And if you combine those two words, you got R+ in a nutshell...

Boy: Bückstabü?
Girl: Oh no, you didn't!

Bückstabü 

A running gag in the darksouls community, played when the "back stab" animation is played.

Originally from a song by the band Rammstein, it's auditory similarity to back stab is part of the reason it's become a joke. How intense it can be interpenetrated as plays the second biggest role in its popularity, as darksouls is infamous for its difficulty and intensity.
