Despite sometimes being considered unworthy of scholarly attention, the study of toilet graffiti, also known as latrinalia, has nevertheless garnered increasing interest among researchers. Graffiti writing still suffers from the stigma of being associated with transgression, vandalism, and a deviant subculture. However, findings from this study show that writing on the restroom wall can facilitate a unique form of communication among the writers. Drawing from semiotic linguistic landscaping and serendipity as methodological inspiration, this research explores data collected from a women's restroom at a UK university over a ten-month period. It examines how restroom users utilized the graffiti-covered wall as a "safe house" and a repository for their anxieties and concerns. The findings illustrate a palpable emotional connection to this specific wall, where writers seek and offer advice, share personal struggles, and provide mutual support to the extent that they see it as contributing more to their mental health than the university does. Through an analysis of the conversational threads present in the graffiti, this study underscores the potential for examining latrinalia within educational institutions to gain valuable and meaningful insights into the student body. The main implication is for educators to consider innovative, non-traditional ways of reaching out to students outside of the formal spaces of learning such as classrooms and libraries. This study, therefore, encourages us to reconsider toilet graffiti as potentially offering an additional or supplementary communication platform for individuals who might otherwise lack the confidence to express themselves openly through traditional means of soliciting feedback.
