VFL
"Virgin For Life" An apt acronym for those who have chosen abstinence (at least until marriage) and 'purity' over the morally flexible sexual trends of their peers. Most often their views and judgements have been instilled by some means of conservative/religious propaganda.

This is the polar contrast to the NPW   
"Dude, check out that blonde sitting over in the corner, she's cute!"
"Don't even think about it Sam, she's definitely a member of the VFL club, trust me."
