Resembling, containing, or having the characteristics of flock; fuzzy, fluffy, or composed of flocking material.
From 'flock' plus the productive adjective-forming suffix '-y' (meaning having the quality of), as in 'fluffy' or 'woolly.'
The '-y' suffix is one of English's most productive—just add it to almost any noun and you get an adjective, which is why 'flocky' feels natural even if you've never heard it before!
