scraggy
1. Bony, scrawny, or particularly lean. The alley was deserted save for a few scraggy street urchins begging for spare change. The main course was nothing but a couple boiled potatoes with a scraggy cut of beef.
2. Jagged or rough. The birds make their nests in the scraggy sides of the huge cliffs. The architect has left the stone scraggy and unpolished to give the building a more naturalistic look.
3. Messy or unkempt. I had a bit of a scraggy beard after the weekend of camping. I can't believe he showed up to the meeting in such scraggy clothes.
