A male who wears too many
Hollister branded articles of clothing. A hollifag will often pop the collar on the shirt he's wearing and possibly wear pre-faded jeans with pre-made holes in them. Hollifags do not care about what is proper or what is reasonable, and they pride themselves in their expensive wardrobes.
The term, hollifag,
may also be applied to
people who wear excessive amounts of American Eagle, Billabong, Aeropostale, etc. due to the similar styles and attitudes found.
