Same as bellend. But this is the way Devvo says it. That chav guy off fat-pie.com

v. collectively or individually finding someone/something to blame for a problem, as opposed to brainstorming which connotes finding solutions to a problem

n. the act of finding someone/something to blame for a problem

(from a TV ad for HD television)

Derived from bellend. Ideal term to describe one who acts against social norms; but without being seen as offensive to other people.
