N + 쟁이

쟁이 is attached to certain nouns to mean someone who does the particular thing(the noun 쟁이 is attached to), particularly if they do it frequently, or they are known for doing that thing (whatever the noun is). Note 쟁이 is usually attached to particular nouns, but sometimes speakers can create their own compound word by attaching 쟁이 to a noun which it's not normally attached to, though depending on the word it may sound awkward.
