1.
(syn foo foo dust, fu fu dust, fu-fu dust])
A non-existant magical dust, used as a metaphor for whatever the hell it is that keeps desireable men in relationships with apprently undesirable women. Probably derived from foo foo or fu fu (the two are synonymous by synecdoche), though the nonsensical nature of the term probably implies that the term could have easily arisen "a tempore."
"Dude, Ben has been dating her for a long time but she is totally lame."

"Yeah, he's totally doped up on her foo-foo dust"
