Moth is a term for a full-blooded Varisian. Because so many Korvosans are at least partially of Varisian descent, the term is quite mild, and is often used to denote the Varisians who still follow their traditional nomadic lifestyle. Among this latter group, the term is sometimes quite offensive, while other nomadic Varisians use it playfully to refer to themselves or others in their social group.
Solly is a shortening of the term "solidarity" and refers to those who wish to unionize or form a guild. It is a very offensive term in Korvosa, where almost all such organizations are banned.
A highly offensive term for excrement or trash that was referred to an unskilled laborer (who were most likely to unionize).
