This article is devoted to the problem of colloquialisms used in fiction. Colloquialisms belong to the sphere of neology and and very often they are used in fiction. The adjective colloquial does not necessarily mean ‘slangy’ or ‘vulgar’, although slang and vulgar vocabulary make part of colloquial vocabulary. Colloquialisms, like familiar and spoken English in general vary tremendously from class to class, set to set, group to group, family to family, individual to individual, and even, according to the individual's mood or aspiration, from one alter ego to another. As an example of the use of colloquialisms the author investigates the work ‘Big Blonde’ of D.Parker.
