Someone that dresses like a Punk Rocker or hard core at night or on weekends, but only with easily removable and undetectable accessories (i.e. fauxhawk) and usually without piercings or tattoos so that he or she may return to the work place or other group setting without appearing to have a Punk Rock affiliation or be a fan.
Janet said she saw her room mate at a party with a fauxhawk, and a leather studded jacket but parts his hair on the left with his corduroy jacket when he goes out with his choir friends. if he was really punk he would have a Mohawk. must suck to be Part Time Punk Rock.
