Back in 2007, I had a HARD TIME when they first introduced the word "sis" here. I agree though and what kills me the most are those lame ass gifs people are still using. That was so 2009/2010. The gifs used to be funny, now people are just making gifs out of the most randomest mess they can find. Basic and unoriginal!!!
lol basically. And now the new thing is "niece" and of course many jump on the bandwagon.
