noun. A violent yet vague something-whatsit.
Real citation: "The sinusitis attack-majiggy
I hateeeeeee it when my sinuses flare up and there's that constant feeling of a strong sneeze coming on, coupled with burning nostrils! Argggh!!! This one nasal spray I am using gives me relief for a an hour at most. This is the one bad thing of Oman. It's so hot everywhere outside that if you are in an air conditioned room and then back outside in the heat one too many times, there are chances of having some kind of allergy/cold situation."
