lurking off 

Gaining pleasure from spying on people online.

I walked into the room and caught Daniel totally lurking off to Stacey's profile.

Lurkin Off 

The act of masturbating in a lurking fashion. This may include, but is not limited to:q
-lurkin off to pictures on social networking websites

-lurkin off in any means of mass transportation (ie. Bus)

-excusing yourself from a social gathering only to go lurk off in the public bathroom.

"Did you see those new pics Jill put on the facebook kid?"

"Boy did I ever, infact I was lurkin off to 'em just this morning."
