When you are covering a DM shift and all hell breaks lose. Stuff hits the fan, then your internet goes out, then your power goes out, then an incident comes in.
Similar to Green FN in NBA 2k but for MLB the show when you perfect a throw from the outfield and "hose" the runner. Also applies to real life when an outfielder makes an incredible throw to "hose" the runner. Stands for "Hosed Fuck N*gga"
