A girl who saves herself for marraige. Typically, this girl is of Catholic or Christian persuasion. Instead of vaginal coitus, she decides to only have sex anally with her partner. This way, she will definitely go to heaven. There are a lot of these girls in the Boston area, hence the name.
She is a wonderfol Christian, always praying, always sacrificing. I hear that she is a virgin still at the age of 27... well a boston virgin at least.
