Top definition
One who disrupts the pace, ryhthm and progress of a Facebook thread by means of their insipid, irrelevant or offensive comments.

A person who by virtue of their lack of wit or perception, inability to grasp sacrcasm or innuendo or refusal to add meaningful or interesting commentary, can single-handedly bring a successfully flowing thread to a brake-squealing halt.
