"Drinking in letters" refers to the practice of wearing Greek letters while consuming alcohol. It is a debated topic among members of sororities and fraternities. Some organizations allow their members to drink in their letters, while others prohibit it. In some cases, members are allowed to drink in their letters but not while wearing the crest. Alcohol is generally forbidden in chapter houses, even if the member is of legal drinking age. It is expected that sisters and new members abide by these rules. While some members may choose to drink in their letters, it is not a universal practice and varies by organization and individual. In general, Greek organizations have rules against drinking, drugs, and inappropriate behavior.
