Tillising
Abstaining from washing one's hands after using the restroom and instead depending on your values to keep one's food from being contaminated or one's hands from being covered in shit.
"Whoa, man-why didn't you wash your hands after you took a dump? Don't you know you could have fecal matter all over your nasty ass hands?" "Nah, it's cool. I'm tillising." "Whatever, dude. Don't you ever touch my fries again."
