Read the passage from Initiation. Millicent brushed back a strand of hair. It was stiff and sticky from the egg that they had broken on her head as she knelt blindfolded at the sorority altar a short while before. There had been a silence, a slight crunching sound, and then she had felt the cold, slimy egg-white flattening and spreading on her head and sliding down her neck. She had heard someone smothering a laugh. It was all part of the ceremony.

What technique does the author use to describe Millicent in this scene?
