Usually a term used by 4 - 10 year olds to describe their underwear. This word is often used by Hipsters because it's incredible ironic and non mainstream. A lot of hipsters are turning to under pants because of their nostalgic feel, it reminds them of their past.
Hipster says: Yo dude check my underpants
Non hipster says: Faggot
