Gleimous ~ Full of phlegm or mucus.
It sounds so much worse to be gleimous than stuffed up, and the visual that comes to mind is slick and repellent. Blech.
Note: I was just trying to find a picture of some poor, sick sod. But then…sick storm trooper! How awful would it be to have a runny nose in that helmet?
