BSF - Best Skype Friend

When you have a best friend, who is on skype.

This could change if you have a better friend on Facebook or MSN

BSF is only related to Skype
Ryan is my BSF. I enjoy sending him poems.

Ben is not a good BSF he talks to other people on skype more than me.

Ben - Hey will you be my BSF?

Travis - No how could you say that? I already have one!
