How come I don't see BUG? We all use this term to refer to the split-bolt connector a.k.a as a Burndy or a Kearney, after the manufacturers East or West.
How about EMPTY (em-t) for EMT?
Greenfield or flex for FMC?
Sealtight for LFMT
OR, SMURF tube for ENT? (for the color of blue it comes in, matches the cartoon critters from the 70s)
