Portmanteau of "friend" and "
stranger" (pronounced like "stranger" but without the "st" and with an "f"), a franger is an individual whom you don't know yet for some
stupid reason have listed, somewhere,
as a friend, typically on a social networking site.
I dropped two hundred frangers from my friends list last
night. I can't believe I let it
get so out of control. Effing *insert social networking site of
choice*!
