[!kid]

i installed a clutch slave cylinder that had zero fluid in it, gravity is not helping me. does anyone know how to bench bleed it?

You don't need to bench bleed the clutch master. Install it in the car and pump it until you get back pressure on the pedal. It can take a bunch of pumps to clear the air, but it will clear. I grab the pedal and work it vigorously.

I actually bled it like you would bleed brakes, I only did it once and it was perfect. Just to make sure that there would be ZERO air in the system.

If you pumped the master that many times and never felt it produce back pressure, the master cylinder is bad. I don't know why you replaced the slave cylinder, but the only reason to do so would have been if the slave cylinder were leaking. Any other problems with the clutch will be the master cylinder or inside the bell housing.
