Hairstyle popular with male hipsters (or lesbians). The hair is short on the sides and long on the top resulting in a shaggy mound on the crown of the head (the puff).
Non-hipster: Your hair looks..."interesting"...have you had it cut?
Hipster: Yes, it's Hipster-puff.
Hipster: Yes, it's Hipster-puff.
