Viral phenomenon (4)

Ross

I believe the answer is:

meme

'viral phenomenon' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for meme that I've seen before include "online phenomenon" , "Question that spreads on the internet" , "Transmitted cultural idea" , "Image etc. that spreads rapidly on the Internet" , "Often trite image" .)

I've seen this clue in the King Feature Syndicate, The New York Times and The Wall Street Journal.
