From pinboard.in: a new christmas traditions.
Bobby, a sweet but naive college sophomore armed with a bough of (plastic) mistletoe, has made it his mission for this Christmas to kiss every boy in his dormitory, Claremont Hall. Things go smoothly until he runs into Cameron, a smug, icy jerk who lives on the top floor.
