Depending on how cool you are maybe if you start singing it they'll stop

Whenever they would start singing it, I would sing

Cha-cha-cha-lava, La-la-la-chicken!

back at them until they got annoyed enough that they stopped.

🤷‍♂️

Go out for a pack of cigarettes, start over.

Mine has largely gotten over the lava chicken phase, and has moved on to the next incredibly annoying barely sentient compulsion.

Last I checked it was the intro to Ducktales. Have you shown them that? It's so ruinously catchy it may never leave your mind.

Record it from all angles at all opportunities and play the video at their wedding. Until then, sustain yourself on the antici

Tell him or her that if it's underground, it's called magma rather than lava.

Unleash the Crazy Frog. Or go nuclear with playing non-stop every single kitsch 70’s romantic songs on repeat—while singing them passionately.

It give’em an hour.

I don't wanna sound old here, but I finally watched that thing a couple days ago and boy did I feel my age there. Clearly I've lived long enough that a whole movie failed to connect with me on any level. I mean it has Jack Black in it and I adore him. I guess what I'm saying is I have no idea how to fix your kid because they're a different people now.

However , the classic old group defense against young slang is taking it up and enthusiastically using it wrong. So enjoy your hot poultry song.

Start singing it with them. Do it sincerely. You'll either kill their joy or you two will have a moment.

I have had this exact issue with that frozen music. You are essentially done. Years later i still recall that music.

See if they like "Yellow Submarine" and switch over to the Beatles?

Make it inhumanely cringe. Start calling everything lava chicken as a replacement for "cool", make lame ass Minecraft dad jokes at every opportunity, yell chicken jockey out the window to summon your spawn in public.

Sing it back to them

La la la lava!

Steady now, my generation got through the Macarena, you'll get through this. Nice deep breaths... in... out...

Try switching to Parry Grip, some of it is OK and the catalogue is big enough they don't really get stuck.

And just to show solidarity the other day my kid just kept 'teenage mutant ninja turtles'ing for what felt like a half hour without a single 'heroes in a half shell' to round it off.

I mean it's not Baby Shark?

Get back at them by singing Peaches from the Mario Bros movie. You know, Jack Black and all that.

Interrupt by yelling "CHICKEN JOCKEY" every few bars.

Sink enough money into lava chicken paraphernalia for the child to instantly lose all interest in it.

Not the answer you're looking for, but this reminded me of a short video I saw a long time ago where it was some kids being obnoxious ( as they're known for ) on a train and this man snaps and screams, in Chinese, "Shut up! I wanna die!" because of how tired he was.

Cannot find the clip when I search for it, but I think it's pretty funny. Nor do I remember where I saw it, but that specific little video thing has absolutely stuck with me.l ever since I saw it.
