Get the Mummug. 
A very well meme put in YTP's, This is LITTERALLY one of best insults you could use in Dream SMP, And a good way to be called a simp and have a comeback using the fact that you probably ARE a simp.
Friend: I've seen watch you've been lately, and 10/10 you're a simp
You: If the following is true then. UR MUM GEY
Friend: No! That is untrue
You: THEN TAKE THAT BACK!
