The act of taking a bathroom trip in which you need to crap when you're with company but don't want them to know you were taking a crap. It involves the preparation of wadded-up toilet paper placed on your lap while your feces is already on the way out. This maximizes efficiency and reduces the time you take to unroll and wad the toilet paper, making what could have been an awkward moment after your party has been waiting for you. For all they know, you just made a tinkle.
I met this girl for dinner last night. I had to shit so bad, but I didn't want her to know that I pooped. So instead, I took a quick shtinkle.
1- left over particles of feces lingering at the bottom of the toilet, nearly unflushable and as fine as silt. 2- Small particles of shit and or toilet paper or other very small pieces of anything lodged in your ass crack after wiping, usually discovered when washing your ass-crack during a shower.
"I tried to flush away the remaining shiticles before my girlfriend came over, but they just wouldn't dissipate."
"I had shiticles lodged in my ass."
"The shiticles in my underwear ended up staining them."
