Newest acronym: GSOD

GSOD: Gerbil Sneeze of Death

Gerbils, by their very nature, tend to hold things in: their emotions, their food, their p--p (!), and, unfortunately, their sneezes. If you don't help your gerbil by opening up their potentially-fatal nasal passages with tweezers (or barbecue tongs, as you see fit), they stand a good chance of suddenly letting loose with a GSOD. Poor little fellas...

Update: GSOD (geesawd) should not be confused with JIHAD (geehawd), in that geesawd is rarely carried out against Western tourists... otherwise, they're pretty much the same thing. Usage: "I declare geesawd against you!"
