no one really knows what the term "big" means in this phrase. you can say it to practically anyone. they'll probably think you mean "fat". but truly, you don't know what it means either. its funny for no reason.

UR is an abbreviation used for Unlock Reality a term which signifies something deep or wise. UR is Unlock Reality

Big Up is a show of respect.

Hense, a UR-Big-Up is a show of respect for something or someone showing depth or wisdom.

These have begun to appear especially on Myspace as comments which start with:

Unlock Reality (UR) followed by a greeting

i.e.
Unlock Reality (UR) Cool!
Unlock Reality (UR) FUN!
Unlock Reality (UR) Fantastic!
Unlock Reality (UR) the one!

If you receive a message like this with a good term at the end, you may feel highly complimented as you have received a UR-Big-Up, indicating that the sender sees you as part of the solution to world problems and not part of the cause.
I found a UR-Big-Up on my page today, it said
Unlock Reality (UR) my sunshine!

made me feel great!

Only for use when "ur mom gay" doesn't hit them hard enough. These worlds will instantly devastate any hopes and dreams they had, fire them from their job, and make all of their family instantly die.

Basically destroys anybody. In some situations it has the power of getting on the same power level level as no u
To boost it's power by 2x , you must say "honk honk" after it.

The immortal "ur" joke. No one can be defeated using this phrase. This is a phrase stronger than Thanos' snap. It can wipe out 75 percent of life on the universe.

person 1: *head implodes*
