"dog" is a meme that was posted by a namefig going by the name of Dominic. This namefig posted a thread on [s4s] with an image of a squirrel and the filename of 'dog.jpg', with this, the post had only the word 'dog'.No association or clear connection can be created by a squirrel and a dog. Maybe this namefig has a connection with swaglord? Or this namefig just is very passionate for the welfare of squirrels? Maybe the squirrel in the picture is running like a dog? Who knows.
The one thing that we have learned from this, is that [s4s] is still a very nice and open community and will accept the birth of new memes and cultures alike.
