This paper concentrated on the description and analysis of conversational topic preferences, use of taboo words, euphemisms and cathartic words. Results of the study showed that past activities is the most preferred topic by male students while love life and school matters were ranked second and third respectively while love life topped the list of female students while school matters and family came next. In terms of topics which should be kept private, among them are those which concern the lives of other people, love life, bad experiences, family problems, and secrets. Both male and female students spill improper words as cathartic expressions to show anger and fright. Similarly, both groups of respondents tend to utter harsh words to insult or hurt other people. It can be noted that although both groups are capable of saying cuss words, there are still those who do not utter such. When it comes to the use of taboo words, female students use more euphemisms to cover terms used to refer to excretory process and those which are closely associated to sexual intercourse. Since the respondents are in their teenage years and most of their time is spent with their friends, friends is on the top list pertaining to the sources of cuss words.
