Mass consumption in the eternal quest for what is cool, distinct, difficult to acquire, or just plain ugly. Hipsters engage in hipsterism by shopping at the most trendy places, always looking for the most unique items. Everything, from the type of clothes worn to what you eat is a status symbol to the hipsterist.
Darren's hipsterism had run rampant by the time he bought his 7th vintage BMW motorcycle.
Someone who walks aimlessly through a grocery store or other public place while talking intently on the phone. Phone zombies are usually clueless about where they're going, who they're blocking, or how stupid they look. Their conversations are usually loud and unimportant, but they don't care.
