No, it stands for "involuntary celibate", but unlike just normal virgins, they become super bitter and blames women for not wanting to sleep with them. They build a whole community that's really toxic and focuses on hating women and men who get laid. Most of them are not even ugly, just can't handle a few rejections and think the entire world is against them. They go as far as advocating rape and one of them even started a mass shooting, another drove a van into a crowd because women won't sleep with them.
