Sketchbook Friend 

During a night of drinking, the first friend to pass out then becomes a 'sketchbook' for all those in possession of a sharpie. This friend is subsequently photographed and posted to Facebook, thus becoming a Sketchbook Friend.

It looks like I'm about to have a new Sketchbook Friend

sketchball 

a.) The noun form of sketchy.
b.) Someone who participates in activities that you wouldn't want the majority of people to know about because people will think you're creepy, and avoid you.

Normal behavior of a sketchball include:
Hitting on girls outside of preppy suburban bars.
Sitting by themselves at night on their sidekick/blackberry
"Accidently" sleeping with people
Lurking people like crazy on facebook/myspace/AIM.

Man, Wesley is such a sketchball, he was lurking that girls myspace at the show, while SHE was at the show, somehow he ended up "accidently" sleeping with her, after he hit on her friend last night.
