If the party guest wants to call his guess a hypothesis, he will need to conduct a research study with valid test procedures. In this instance, a questionnaire or interview conducted on a random sample of people of different age groups, genders, socioeconomic statuses and ethnicities will provide findings that can either prove or disprove the hypothesis.
Your friend is incorrect for the following reasons. In order to call his idea a hypothesis, it would need to be formed on limited evidence and could not be "well-educated". Additionally, this hypothesis would need to be falsifiable, meaning that it could be proven wrong. Finally, the hypothesis would need to be testable.
