For when you need a laugh!

The definition of a "meme" here is intentionally pretty loose. Images, screenshots, and the like are welcome!

But, keep it lighthearted and/or within our server's ideals.

Posts and comments that are hateful, trolling, inciting, and/or overly negative will be removed at the moderators' discretion.

Please follow all slrpnk.net rules and community guidelines

Have fun!
