Craigslist slang to indicate that a forum post has received some flags. This is also the basis for "buzz!" When a forum post is flagged, the following haiku appears:
thanks for flagging this
staff will look at it shortly
hey, a dragonfly!
Dragonfly references mean that the thread is destined to be Isled soon.
(ranting idiot) OH YEAH I HATE YOU NATZI FLAGERS! GET A LIFE!
(forum poster) Buzz.
(second poster) Dragonflies!
