Colloquial, conversational, informal refer to types of speech or to usages not on a formal level. Colloquial is often mistakenly used with a connotation of disapproval, as if it meant “vulgar” or “bad” or “incorrect” usage, whereas it is merely a familiar style used in speaking and writing. Conversational refers to a style used in the oral exchange of ideas, opinions, etc.: an easy conversational style. Informal means without formality, without strict attention to set forms, unceremonious: an informal manner of speaking; it describes the ordinary, everyday language of cultivated speakers.

Explanation
Colloquial language is casual and conversational: it's the difference between "What are you going to do?" and "Whatchagonnado?" The word colloquial comes from the Latin word colloquium, which means "speaking together." The roots are the prefix com-, which means "together," and the suffix -loqu, which means "speak." Some may think that colloquial language is not good, when in fact it may just not be appropriate for the context. While it is OK to be colloquial and chatty with friends, it is not acceptable to be colloquial in an essay for school or work.
