can we just get rid of the tag entirely since newfags can't tag? I don't mean to sound like I'm mad but when I look up a meme on the internet, I don't want to be forced to stare into the palm of my hand at 0.1 centimeters.

well, the tag doesn't actually exist. search it, then click a pic. look at the tags, "dat_ass" doesn't appear.

It's an alias:
