To big something up, either through hyperbole, or literally. Derives from Walt Whitman's use of a) very long lines in his poetry, and b) a very large beard on his face.
Cf. alginsbergification, which is similar in meaning but usually connotes either an imitative approach to waltwhitmification, or a homoerotically charged adaptataion of same.
1) Kevin really needs to waltwhitmify that beard.
2) That chick's boobs are totally waltwhitmified!
3) Al Ginsberg's poems could be seen as derivative vis a vis the waltwhitmification of the line.
4) Dude, don't waltwhitmify that shizzle -- you know it was totally not cool.
NB the passive voice is generally considered acceptable usage, as it aids in conveying the extended lengthiness that waltwhitmification embodies.
