ghost medic 

The ghost medic is where you apply a tourniquet to either arm, wait until the arm loses feeling, then utilize it to masturbate with.

Private: Doc, I totally tried the ghost medic after I stole a tourniquet from CLS class! Shit was so awesome!

Medic: I swear, infantrymen are some of the strangest people I've ever met.

Social Media Ghost 

Social Media Ghost is an Internet phenomenon that effects only a few people on social media, Internet forums, etc. Social Media Ghosts are people who are generally unnoticed online, thus generally unable to make friends or get replies/reactions to their posts, regardless of the content they post.

There doesn't appear to be a primal reason why some people are SMG, and others aren't.

Social Media Ghost isn’t contained to one website, but the entire Internet. Someone doesn’t have any followers or replies on one social media site or forum alone isn’t SMG.
Although much more rare, it seems to be possible for people who have friends offline to be SMG.
