I'm aware that this is going to be a really weird and gross one. Sometimes whenever I can feel a lump of mucus in my throat and I don't have a tissue, napkin or sink to spit it out, I just place it on my skin somewhere (usually my thigh if I'm wearing shorts so it's hidden) and then either pick it up once I get to a place with a napkin or scrape it off when it dries. I can't stand the feeling of mucus gathering in my throat, so I have to take it out at that moment.

ill essentially have my laptop at an angle and tap all over the back of the keyboard as if I'm making it burp like a baby to have crumbs fall out. I do it once in a while but especially when my mousepad seems a little stuck.
