There are two different types of wedgies. One occurs naturally when a person's underwear or other garments are wedged between the buttocks. Another occurs when someone pulls a person's underwear between the buttocks as a prank or as a form of bullying.
Within the context of psychology, social psychology is the scientific study of how people's thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. By this definition, scientific refers to the empirical method of investigation. The terms thoughts, feelings, and behaviors include all psychological variables that are measurable in a human being. The statement that others' presence may be imagined or implied suggests that we are prone to social influence even when no other people are present, such as when watching television, or following internalized cultural norms. Social psychologists typically explain human behavior as a result of the interaction of mental states and immediate social situations. In general, social psychologists have a preference for laboratory-based, empirical findings. Social psychology theories tend to be specific and focused, rather than global and general.
Social psychologists therefore deal with the factors that lead us to behave in a given way in the presence of others, and look at the conditions under which certain behavior/actions and feelings occur. Social psychology is concerned with the way these feelings, thoughts, beliefs, intentions and goals are constructed and how such psychological factors, in turn, influence our interactions with others.
