Deb = shortened form of girls name (but even then a girl called Deborah would normally be called by the shortened form Debs, rather than Deb) - these go well with .com or org but I am not really sure of it with .biz - in what way is Deb associated with business?
I know you have debutantes and sure there must be some money changing hands with them but I would expect that to also use the shortened form "debs".
IMO this one really only works for a female desperate to own a Deb name or for a business who's initials are D.E.B.
Now if there was a "t" on the end .... sigh
