Mama Licker 

Someone so lame and out of touch with society. Their natural habitat is within their mother's basement. In most scenarios, these people are of forty-year old virgin status.

Jeff: "Look at Larry playing League of Legends"
Martin: "Isn't that guy like 45?"
Chris: "Yea, what a Mama Licker!"

Can be associated with motherf***er but is most often used online. A cleaner way to get your point across, especially when around kids.

“Did you just see that mamalocker six me!?!?”

“God…. I hate that mamalocker.”
