The paradox that occurs when trying to simultaneously imply that Justin Bieber is both female and homosexual, yet not a lesbian.
*male joins a group of friends*
1: "I had sex with a girl that just turned 18 last night."
2: "You mean Justin Bieber?"
3: "There's no way it was a girl. So is Justin Bieber a good top?"
1: "You guys suck. And you need to decide on if Bieber is gay or a girl, the Bieber paradox is messing with my head."

1: When the very flow of time colapses upon in itself due to a temporal incursion or "Time Travel" Noteworthy people who have gone backward in time would be...Well, that guy in Timecop....Shut up.
Anyhoo, don't go back in time, because you'll only crush a mosquito and destroy Berlin.

For more information on time paradoxes, Play TimeSplitters: Future Perfect. or watch a ST: Voyager episodes when it goes back in time...They have it down.

2. Whatever went on with Red Foreman and that big ship in Star Trek: Voyager. Like, seriously, WTF? Temporal Shielding? And why could they live forever if they're protected from time. They'd age normally! Sorry, it's just the fact you could erase places from time looks cool, but is just not feasible.
"What the hell, you're me!"
"Yeah, I knew you'd say that. Take this key, it's for that door. You won't make it through without it."
"If you couldn't make it through, who gave it to you?"
"I did"
"What?!"
"Just shut up, I gotta go and save us from a big snake"
"If you're me, then-"
"1978"
"But when"
"Yesterday"
"How-"
"I'm you right?"
"Oh yeah....How many fingers am I holding up?"
"I'm you, I'm not psychic....4"
"F%$#!"
"Really, now go on ahead through that door, and watch out for...Never mind"
"Huh?"

Science fiction likes to make a big deal out of this term and throw technobabble around to make it look clever in an attempt to make the audience confused and thus ready to buy whatever crap the writers come up with.

Basically, a time paradox occurs if you time travel and change the past so that it erases the possibility of you going to the past in the first place. Which means that events will occur as if you never traveled to the past, undoing your changes so you will travel to the past again, and so on ad infinitum.

Some writers think that it can destroy the universe. Or unleash killer flying time monkeys. Well, we haven't invented time travel so we can't test these theories.
- So, if I travel to the past to kill my grandfather, I'll create a time paradox and will never been born?
- Worse than that - if you travel to the past to kill someone and succeed, then you will have no reason to travel to the past at all! And without you in the past, events will happen as they originally did before you interfered. Time will be caught in a loop!
- Oh no!

another word for the end of the world, this is in relation to the way a phrase contradicts itself because revelation is rhumoured to say that when the world ends everything contradicts itself all at once in all forms and starts the end of the world.
