It's not enough for me to just hack up loogies (wet, juicy boogars you usually bring up in your mouth).
They can be sticky mucus sometimes and they aren't always easy to spit out. You shouldn't swallow them as you'll want to throw up later.
So often I take them off my tongue with my fingers. But then I can't get rid of them. I start rolling them around and playing with them in the way you play with rubber cement balls.
Does anyone else do this? When you're coughing a lot, do you sort of try to combine loogies to make bigger the biggest loogey?
I'll wash my hands before I shake yours, but this is an addictive habit.
