Online chuckle (3)

Ross

I believe the answer is:

lol

'online chuckle' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for lol that I've seen before include "Very funny (1)" , "so funny online!" .)

I've seen this clue in the Newsday and the Universal.
