Ipso facto is a philosophical term. It is Latin for "by that very fact".
'You work for the bank. The bank works for me. Ipso facto, I'm your boss.'
--Ben Stiller in "Dodgeball"

This word is typically used to emphasize a contradition, and its use as "by that very fact" should be distinguished from therefore, which also means "by the preceding fact". In the example below, ipso facto is used because the success in some way hinges on apparent failure. This could occur if, for example, if my goal was to lower myself in the other's opinion. Ipso facto, then, is almost always used to emphasize problems of perspective, as in the example.
He says I have failed, but, ipso facto, I've succeeded.

Or a choice:
"Dulce et decorum est pro patria mori."-A Line from Horace later used by Wilfred owen in a WW2 poem, ipso facto, whats right is right and past be the past, I will too.
"In flagrante delicto-caught red handed- Ispso Facto, you are a coward hater, not family until your calm your shanangins down."

"The man told the trusting woman that they "men" were taking a mountian trip while she went home to her dying grandmother. Ipso Facto, he/she were lying to one another and not only with one but several college students the woman knew nothing about. Again Ipso facto, how many spawns may he have he deny's?
