Zombie Jokes And Puns

Hello,

I am requesting help with remembering a joke. Posts of this type did not seem to be against the subreddit's rules, but if I am in error, please let me know and delete my post.

Anyway, here is what I remember of the joke:

It is movie themed and it says something like this: "There should be a post-apocalyptic zombie movie with a romantic comedy element. Then we would have the world's first rom-com-zom-dom-bomb." The only thing is that I forget what the "dom" was supposed to mean and whether or not there is more to this joke, either in the set-up or the punchline. I googled it to no avail. Any help is appreciated.

Thank you

I will now take suggestions on how to be more sensitive to deaf people. I'm all ears!

Background: I'm living in Germany and have a German roommate who can speak some English. He did Realschule (completed 10th grade), but mostly ditched classes. I try to teach him when I can and vice versa.

We were watching Walking Dead. The episode was right after the prison gets stormed. Rick and Carl lock themselves in a house, and Carl ties a knot that he's super proud of... Blablabla... A few minutes later, knot is quickly falling apart as zombies try to break in.

I absentmindedly said: "Cool knot, bro" Roommate: "(K)not cool, bro"

I just looked at him with a mixture of surprise, pride, and wondering still if he knows what a dad joke is.
