Let me guess, you were lighting and/or gaffer? No idea what a mighty mole, hi-hi-boy, half CTO, scrim, baby, baby-baby, or "trombone" are. But they sound to be different styles of lighting gear and various accessories.

I'd say the 5k is a VERY bright light and ND means it can be "notched down" to produce a lower illumination. Western dolly probably refers to one on rails and a crank-o-vator is likely a scissors type extensible tower platform made for rigging gear.

I'm guessing on all of this, but:
Mighty-mole = some little light cans that put off a lot of light for their size
Hi-hi-boy = a crane or scaffolding for equipment
half CTO = color filter of some sort?
Scrims = no idea
baby/baby-baby = larger cans of the same lux as the mighty-moles, but more painful to deal with? Older equipment I mean.
trombone = some rigging that allows the items to move back and forth for focus?

Okay, how did I do? Do I win a shiny new nickel?
