A Felix (noun) is a literal term for a big, messy
shit or a figurative term when it relates to being in trouble. Its origin came from a man of the same name who developed a reputation for leaving big,
stinky shits un-flushed in the toilet, accompanied by a dirty wipe
rag lying on the floor next to the toilet.
"I ate so much
BBQ last night, I'm on my third Felix of the morning!"..." or "I'm going to be
knee deep in a pile of Felix if I don't finish this in
time!"
