jacksnt 

Someone you don't want to be friends with. An example of a jacksnt would be someone who starts drama between friends, is unwanted among activities and ruins the mood. A looked-down-upon type of person in society, and an undesirable name to be called.
Named 'jacksnt' as it was originally used to refer to people with the name Jack/Jackson, but it has since broadened to any name.

"I'm not too fond of Phillip at the moment, he's becoming a jacksnt."
"I would stay away from jacksnt's at today's party, we don't want to ruin our mood!"
"Jacksnt's are the reason it's hard to make friends nowadays."
