Subsidized prefix: anyone know what this means?

I have a Heart Breaker legendary with the prefix Subsidized Viral. I think Viral means added DPS but I can’t find any info about what subsidized means. Anyone know?

I have tried to figure this out as well and haven’t found it on any prefix list. What I have ascertained is that it is a Hyperion-specific prefix and the only weapons I ever see it on are shotguns. The common trend seems to be damage reduction and consumption of 2+ ammo per shot. Let me know if you figure it out!

more mag size , i think viral mean corrosive ?

prefix can be related to bl2 , like x2 = redundant
