FAO
From Waccoepedia
FAO is an acronym that stands for: For the Attention Of and is often used in the subject title of a new post by people who don't understand how the PM system works.
example:
"FAO: Poster A"
Is she really going out with him?.....
One exception to this rule is when the PM Box of Poster A is full.
example:
"FAO: Poster A"
Empty your PM Box I need to talk
In normal WACCOE usage, i.e. in Fucktard speak, "FAO" is followed by "of", and then the other poster's name, as in "FAO of Dipstick".
