look up any word, like usuratonkachi:
 
1.
A feeling of nausea, typically accompanied by uncontrollable flatulence; often leading to gross and ill-timed defecations.
Friend: "Hey man, you don't look so good."

Me: "Yeah, I'm feeling a bit fecescious. It was probably the Taco Bell."

Friend: "I feel that. Just make sure you don't diarrhea all over the place."
