Shitty Ask Lemmy

whip them until they start listenin!
Lick their ear.
Less intrusively, just vomit! Anywhere any time. 100% Always gets people's attention. Works better if you don't have to stick your finger down your throat first.
i just stop bothering when i notice it.
great question btw, this is supposed to be shitty asklemmy.
I was hoping for shitty answers telling me to severely overreact
then you can always tell them to go fuck themselves.
the thing with people that won't listen is that sometimes you can go crazy with the whole making them mad for fun thing. if you dedicate yourself to breach their bubble a lil bit, you will often find the bait that will make them RAGE, and it gets funny as fuck.
I'm sorry, what?

El duderino if you're not into the whole brevity thing
I stop talking until they look away from their screen.
In the middle of a sentence, scream. Scream like you're being murdered with a rusty spoon and you don't like it. When they look at you, scream louder. Run into the woods, don't stop screaming.
Stop talking and walk away
FWIW I don't listen to anyone who doesn't sign my paycheck, you're all just noise
I start talking completely nonsensically. I have a gift to be able to just start rambling in a way that sounds like im saying something coherent but when youre actually listening to it, im really not making sense. Ill do that until they catch on. I do it to my kids a lot.
That’s like the time I caught the ferry over to Shelbyville. I needed a new heel for my shoe, so I decided to go to Morganville, which is what they call Shelbyville in those days. So I tied an onion to my belt, which was the style at the time. Now, to take the ferry cost a nickel, and in those days nickels had pictures of bumblebees on ‘em. “Give me five bees for a quarter,” you’d say. Now where were we? Oh yeah! The important thing was, that I had an onion on my belt, which was the style at the time. They didn’t have white onions, because of the war. The only thing you could get was those big yellow ones.
