"Hey dude, that loser over there is sitting all alone, should we help him?"
"No man, he's an insig, he thinks he's cool."

An involuntary single. The female equivalent to a male Incel. One who can obtain sex, but cannot obtain a serious relationship with a man she truly loves, admires, and respects.

Mary is such a insig, no dude will ever claim her.
