A reference from a BBC Sci-Fi television series, where the main protagonist, the Doctor, tries to explain time to a character in the episode named Sally Sparrow. And describes that time is a big ball of "wibbly wobbly timey wimey stuff." Or a ball of time where you can take any path alter any time line. Which is true, proven by Astrophysicist, Neil Degrasse Tyson.
Now used to describe something as very confusing.
People assume that time is a strict progression of cause to affect, but actually, from a non-linier, non subjective point of view it is more like a big ball of wibbily wobbly timey wimey...stuff
