When a boomer gets so fed up with millennials, they get a boomer tumor. A boomer tumor is a swelling of the brain that only occurs in people from the boomer generation. To them, all millennial humor is just nonsense bullshit. The swelling is caused because they have no fucking clue how funny a meme is, so they get confused. Boomer Tumors are fatal, and luckily, will finish off the boomers soon.

Get the Boomer Tumor mug.
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?
