The secret backwards word for "SuckMyDick". If you are in a situation where you cannot use the correct form of "Suck My Dick" and you are angry with someone, just break out the word, "KCidyMkus" instead and you will feel better.
Here is an example of when KCidyMkcus could come in very handy!
You: Hey, what's up? Church is sure boring today, isn't it?
Jordan: Yeah, it really is extra boring today. But I had a great time last night.
You: Oh really, what did you do?
Jordan: Oh, I had sex with you girlfriend. She really is amazing in bed.
You: You....You.....You KCidyMkus!!! I'll see you after church in the parking lot!
Jordan: What the hell did you call me?
You: Muhahahahah! That's for me to know and you to find out!
