A person who doesn't know how to have any relationship because of their lack of social skills and their desire to do nothing but be online.
My son is a camjam. He does nothing but cry and watch memes all day with no sleep.
When the camgirl you've been tipping and chatting with charges you a high price for a private show, only to shut down due to "a friend stopped by", technical difficulties or any other bullshit excuse to rip you off.
So how'd it go when that slutty camgal you've been sexting with?
Shit, I should have known I was gettin' camjammed when suddenly she had to reboot and never came back on
