Know That

The term is commonly used at the end of a statement, primarily to emphasize the factual basis of said statement.

It can also be used to educate others of your self-importance or emphasize others' faults.

The term was popularized by Allison Dubois on an episode of the reality show "The Real Housewives of Beverly Hills - Dinner Party from Hell."

Allison: "I have books written on me and by me and television shows based on my life so you can just take a flying leap. Know that."

-or-
