Hammerface is the old scary look that Herion Addicts develop over time, beautiful smooth bodies and ugly old scary Hammerfaces.
Refers to the old name for Herion (Hammer.) These days could probably refer to Meth too.
Person 1. See that stripper - her body totally doesn't match her face.
Person 2. No shit, she has a Hammerface for sure.
