Definitions by Grand Al

zent 

To post a message on a social networking site about one's current state of mind with the intention of reminding people that you exist. Similar to vaguebooking.

Seems to be derived from a mix of "representing" (as in fronting) and "venting".

Is Kev zenting again? Ignore him.
also as a noun:
Lame: my twitter feed is always just a load of zents
