The worst insult ever known to mankind. It means that someone is not only a prick, they're the whole cactus. This extremely offensive word was believed to have originated in the Medieval ages or before that. It is the worst insult ever. 'ur mom a cactus' is even worse than 'ur mom gay', 'ur papa a nazi', 'ur gran gran a trans man', 'ur dad a lesbian', 'ur cousin a muffin' and the N word. It is not a bad as 'ur mom trans' and 'ur papi nazi'. This word is also worse than 'Karen'.
Karen: Why did you block me? Ur mom gay.
Donna: Ur mom a cactus.
Karen: That hurts.
Donna: Just avoid ur mom and you'll be fine.
Karen: I'm gay.
Donna: Yes.
Donna: Ur mom a cactus.
Karen: That hurts.
Donna: Just avoid ur mom and you'll be fine.
Karen: I'm gay.
Donna: Yes.

Ur mom is hot, funny, sweet, intelligent, and, well, your mom. You never want to lose her, neither will the men,😉. She is the best person to have in the world.
