"The Kewlest Thing of All", David Ira Cleary

NT ASFM Mar 2006 - science fiction
<<- Asimov's Science Fiction Mar 2006 cover by J.K. Potter for "The Kewlest Thing of All"
Genuinely cool girl Bonny Brood, who has a videophone embedded in her palm and browser windows across her skin, is guerilla marketing "kewlness" to fat and uncool Katelyn Sayed. Bonny is blocking Katelyn from being branded by corporation Steward International for this guy Terrence. The setting is a future San Francisco after melt waters flood the city.

This seems like updated cyberpunk. It humorously includes a girl on girl crush. The ending confounded me somewhat, but I'd recommend this novelette.
