Gaiger
A super gross feeling in your throat from eating or smelling something so bad it's like your stomach is trying to escape.
I got Gaiger from my mom's smeggy falas. I had to run outside to puke.
At the movies, I got Gaiger from the person behind me eating a whole bag of popcorn.
During my math test, I got Gaiger from the smell of my neighbor's falas.
