This document discusses several linguistic features commonly used by teenagers, including phatic talk, vague language, omission of copula verbs, use of slang words, and lying by omission. Phatic talk and vague language are used to seek attention. Omitting copula verbs and using slang like "suck" instead of standard language is considered cool among teenagers. Lying by omission to friends is also discussed as a way for teenagers to avoid telling others everything about their lives.
