Post nasal drip 

Something that I suffer with all the time every day of my life, and it friggin sucks. Basically your nose sinuses are so stuffed to the point that the snot "drips" down to your throat, and it makes you gag. Not really a big deal if it happens infrequently, but chronic post nasal drip is literally hell.

Me: Hey guys how's it g— *gags loudly on snot*
Them: Woah you okay there dude?
Me: Oh dw it's nothing, just my typical post nasal drip.
