This design has been in my mind for a quite while. Do any of you know how to create/identify this kind of typography? I need some help because this kind of design intrigued me a lot.
Assuming you're only talking about the (mix of) typography, since that is the feature jumping out, this is actually known as the ransom note effect:
In typography, the ransom note effect is the result of using an excessive number of juxtaposed typefaces. It takes its name from the appearance of a stereotypical ransom note, with the message formed from words or letters cut randomly from a magazine or newspaper in order to avoid using recognizable handwriting.
I would not call it really a "typography style", as it is a random collection of styles.
However, from an artistic POV, I would call it a collage. It is a collection of cropped pictures, each picture containing a letter (or other symbol) with various type settings.
