Ghoster 

1)Usually a guy who you meet (either online or in some random encounter) who seems to be your soulmate because he likes all the same music and all the same movies, he tells you how amazing you are and says he wants to have a serious relationship. Then when you want to meet him again (or for the first time in person if you met online) he says he is super busy but he really wants to see you soon... then he suddenly stops being in touch with you, ignores calls, cancels any plans you made, changes his number, blocks you or seems to vanish from the face of the earth. Essentially he is so sweet you cannot understand why he would not be answering unless something terrible happened like he died and you have no way of knowing. He becomes a ghost. He haunts your thoughts and you can never figure out what happened.
Similar to when someone is a catfish except that often everything he said about his favorite music and where he went to high school etc. was really true but he has lied about one thing that he doesn't want you to know like he is already married or he said he had a job but he is really unemployed and broke and doesn't want you to find out.
2)Also a real boyfriend who loves you and treats you like a princess... until he finds someone better and doesn't have the heart to break up with you because he thinks it is too difficult to break up and he is a scared pansy ....so he just blocks you and unfriends you on FB and totally vanishes without a word.

Girl 1: My boyfriend hasn't called in a month... I hope he is okay... do you think he maybe broke his phone or lost it?
Girl 2: No hun, that guy is a ghoster and you are never gonna see him again so move on before you go crazy wondering what happened.

Ghost Audio 

The few seconds of audio a computer makes after a window is closed that was playing audio. A lul usually occurs between the closing of the window and the few seconds of audio. This usually happens with aged computers and tends to happen more and more as time goes by.

Music Player: "Play that funky music white boy
Play that funky music right
Play that funky music white boy"
- Window Closes -
3 Seconds Later...
Music Player (Ghost Audio): "'Till you die."
