adj. pertaining to slang, expressed in slang, that contains slang

Slang is the use of highly informal words and expressions that are not considered standard in the speaker's dialect or language. Slang is often highly regional, specific to a particular territory.Slang terms are frequently particular to a certain subculture, such as musicians, and members of minority groups. Nevertheless, usage of slang expressions can spread outside their original arenas to become commonly understood, such as "cool" and "jive". While some words eventually lose their status as slang, others continue to be considered as such by most speakers. In spite of this, the process tends to lead the original users to replace the words with other, less-recognized terms to maintain group identity.
