I know what you are talking about, Impala. For the most part, I think that people just refer to "my boyfriend"/"my girlfriend" instead of using their actual name when the group or person they are talking to is not very familiar with their BF/GF. Though, I do think that in some situations individuals can be insecure about there relationship status, and feel the need to boast that they actually do have a BF/GF! Who knows though, right?
