Aim of this paper is to detect determinants and to suggest a typology bullying. Four network samples of 218 students in total (male = 92, female = 126) at the Physical Education and Sport Sciences Dept. and the Veterinary Dept. of the University of Thessaly have been collected in 2017. Standardized questionnaire composed of network and non-network part was answered. Social network analysis and cross-sectional statistics (Spearman test and Principal Component Analysis) were implemented. Basic results: Female gender and traveling abroad for sport, the desire of distinction in science and the social selectiveness tend to protect against bullying. High semester, tallness, high educational influence of family and cyber-bullying increase the susceptibility to victimization. These who have experienced bullying as children still tend to experience exclusion. Libeling may even be a reason for not attending lectures. High grade seems not only to protect but also to discourage someone from practicing bullying. Science ambitions seem to be related with elitist ideology, unlike professional ambitions which seem to be related with humanism or sociability. Social selectiveness based on politeness and friendliness also retains the practicing of bullying. Five types of bullying targets have been depicted: “full victim”, “apprenticed”, “libeled scapegoat”, “ridiculed scapegoat” and “gladiator”. Three types of practicing bullying are formulated: “stimulating victimizer”, “provocateur” and “egoist inspirator”.
