The Free Hugs Club is one of the school clubs Greg discusses during Hard Luck.[1]
The club was "on the fringe" according to Greg. When they see someone having a rough day, one of the Free Hugs Club member will hug them. However, they do not ask for permission before hugging the person, and whether or not the person had had a rough day was judged by pure guesses. This is evident when two members walked up to Greg with their arms outstretched.
