gaggage
A gross reaction people get when something is so bad it makes them want to vomit. It can also be a silly joke that makes you laugh until you cry.
My cousin ate a whole plate of spaghetti and meatballs. He looked like he was gonna gag and die.
That kid made a fart joke during the school play. The whole class was gagging and laughing.
I saw a rat in my cereal. I gagged so hard I almost threw up my coffee.
