alumnoid
alumnoid (noun): resembling or having the form of an alumnus
An alumnoid is someone who gives every outward indication of having attended or graduated from a particular college or university, but in fact has not. Identifying traits include: owning and wearing multiple articles of a single college’s logo gear; rooting for the college’s sports team with greater enthusiasm than do allumni…or players…or cheerleaders; steering casual and unrelated conversations to include the school, irrespective of topic. “I thought Chad went to Duke, because he’s always wearing a Duke sweatshirt and freaking about about their basketball team, but it turns out he’s just an alumnoid.”
