To forcibly introduce a change-adverse individual to something new. Similar to dunking a hermit crab in its food and water bowls when introducing it to a new cage.

The process is usually performed for the benefit of the person being hermadunked, but against their will.
“Hey Carolyn thinks that crutons and brocoli have flavor, lets drag her to an indian place and hermadunk her till she learns what flavor is.”

“God damn it, I’ve told you about sushi 30 times, prepare to be hermadunked!”
