When a board suffers from group think and stagnation, sometimes one poster will create a new account and log in to tweak the other posters into a flame war. The Troll for a Day will announce they are a TFAD (TFADing) and everyone will congratulate the regular after getting over their murderous impulses for bringing the community back to life. Some argue that TFADing is a valid tactic for a board administrator to re-spark interest in a community and should be applied when the situation requires it as long as all suspecting members are silenced in a swift fashion.
Posters on message boards who have experienced this behavior will immediately try to label all newcomers as "Troll For a Day".

A person who wears green on st patrick's day but conceals the green so that when they get pinched they reveal the green so that they can pinch someone back twice.
Doug: *pinches chris*, ha! your not wearing green!
Chris: *undoes sweater* here's two pinches! LoL u Mad?
Doug: Ah I didn't know you were a st. patrick's day troll!
