I realise most of us have not been involved in 4chan, 7chan, Reddit and PUA so I have compiled a list of definitions from various websites. Feel free to add to the list:
Cock carousel
The idea is that women want to have sex with as many "high quality" men as possible, moving from one to another quickly and without thought. Usually happens before settling down with a Beta.

Game/Gaming
Techniques used by pick-up artists (PUAs) to manipulate women into having sex.
Gymcel
An incel who copes by going to the gym. Gyming is a cope which can make them happier but will never allow them to change the fundamental fact of their incel status.

Looksmax/Looksmaxxing
The practice of trying to enhance one’s appearance via methods ranging from buying nicer clothes to gym training to radical facial reconstruction through surgery.
Mogged/Mogging
The act of eclipsing another person in terms of physical appearance and thereby undermining them.
"AMOG" originally referred to the "alpha male of a group" in pick-up-artist culture, but the term seems to have evolved into a verb meaning to be emasculated by another man who is bigger, more muscular, or otherwise “better” than oneself.
