When someone knows he has terminal cancer, and he defuses the sadness for others, quite bravely, by hiding his pain around loved ones.
John: That woman is gorgeous. And by the way, your sister is such a sweetie.
Jill: I agree.
Later. . . .
Jill: What happened to John, sister?
Fran: Oh, he passed away. You didn't know he had terminal cancer? Didn't you see the bandage on his ear?
Jill: I suppose he was just implementing tumor humor for me. I never knew about John's cancer.
Fran: May he rest in peace.
Jill: I agree.

When a boomer makes a joke that is really bad. So bad infact, you feel sick... You say you have a Boomer Humor Tumor.
Dad: Hey son what're you doing?
Son: Videogames
Dad: Back in my day we didn't have videogames. Just dirt. And we had to have fun anyways. We walked miles to get to school through swampland.
Son: That gave me a Boomer Humor Tumor.
Dad: What did you just say young man?
Son: Videogames

When somebody makes a really bad joke, or (even though is seems there's no such thing as) a bad pun ( :O )
Dave: "What did the fish say when he swam into a wall?
Dam."
Steve: "... Tumor Humor, Dave. Tumor Humor."
Dam."
Steve: "... Tumor Humor, Dave. Tumor Humor."
