The Merriam-Webster dictionary does not list "front" as a verb.
Dictionary.com provides the following definitions for "to front":
-to have the front toward; face: Our house fronts the lake.
-to meet face to face; confront.
-to face in opposition, hostility, or defiance.
-to furnish or supply a front to: to front a building with sandstone.
-to serve as a front to: A long, sloping lawn fronted their house.
-Informal. to provide an introduction to; introduce: a recorded message that is fronted with a singing commercial.
-to lead (a jazz or dance band).
-Phonetics. to articulate (a speech sound) at a position farther front in the mouth.
-Linguistics. to move (a constituent) to the beginning of a clause or sentence.
You'll note none of these definitions correspond to how this thread uses "to front."
It is therefore incorrect to say that "EVERYONE" uses this term. It is safe to say your average 5-year-old does not know what it means to front something, because most young children do not know street slang. It is equally safe to say that your 85-year-old grandmother does not know what it means, either.
