Common response to posts that are meant to be clever or funny. As many other responses like "O RLY", this has taken on mutliple, and even contradictory meanings.
- The post is too obviously derived from something else (usually whatever forced meme is making the rounds at the time) and thus not quite as amusing as it could have been, or it's just too plain hard to understand.
- At first I didn't see what was funny about that, but now I do. Nice job. Synononym: An image macro saying "At first I was like.. " (Serious look) "But then I LOLd" (laughing face).
- HA HA HA!
