|1.||social acceptance morph|
a social acceptance morph (SAM) is a person with a servile need to be liked. This person has a fluid personality that changes depending on the social situation or whom they are with. Social acceptance morphs are the people usually described as "nice" or "sweet," and they are often the most popular people in any given situation. Upon meeting a SAM, you will feel as if you have met your new best friend--someone who shares all your same interests and laughs at all your jokes. For this reason, a SAM has many infatuated admirers and people who think they are really good friends. Unfortunately, these interactions are not authentic. In most cases, a SAM has very few real friends. It is the tragic circumstance of a SAM that s/he, because of the constant need to please and morph to suit those around, has no real idea who s/he is.
