gaggage
A nasty reaction people get from something gross. It can also be a joke that makes you laugh so hard you fall out of your chair.

That kid told a joke about poop. The whole class was gagging and laughing like they were in a comedy show.
I saw a worm in my sandwich. I gagged so hard I almost screamed.
