You don't have to use gyroelongation

Standard "they don't know" meme format, featuring line art of "That Feel Guy" wearing a party hat standing in a corner while other people are dancing. An image of an icosahedron formed by three mutually perpendicular golden ratio rectangles sits in front of That Feel Guy. The caption text says "They don't know that three mutually perpendicular golden ratio rectangles, with edges connecting their corners, form a regular icosahedron."

I spent a good minute trying to work out how you could get 20 sides when theres only 4 edges per rectangle, 12 edges is not quite 20

Not my finest moment

for a minute you were one of this filthy casuals just dancing with no understanding of the geometry of planes and shapes.

Are they rotoated around the center or how are they positioned?

Mutually orthogonal is a mathy way of saying at right angles to each other. No rotation, think of putting the rectangles on the 3 planes of a 3-axed coordinate system.
