Shituational Awareness is awareness of your environment whilst taking a dump, or pitching a loaf. Poor shituational awareness can lead to lack of toilet paper, or coming face to face with a former dumpee's turd. Can also lead to entering a toilet with a broken lock.
"Dude, have some shituational awareness about you when you pitch a loaf, the paper has run out!"
