I've found a tongue twister from my second language:
კაპიკი გაკაპიკებულა, საკაპიკეში ჩაკაპიკებულა
kapiki gakapikebula, sakapikeshi chakapikebula
I don't know what it means though
Also, we have this word that sounds like a tongue twister: გვფრცქვნი - gvprtskvni which means "You peel us". (If you wonder now - Yes in Georgian there are pronouns but the conjugation already tells you who does what to who, with suffixes and prefixes)
De kat krabt de krullen van de trap. (The cat scratches the (wood-)curls off the stairs.)
De knecht van de kapper knipt en kapt knapper dan de kapper knippen en kappen kan. (The hairdressers assistant cuts and dresses better than the hairdresser can cut and dress.)
A couple of English ones:
She sells seashells by the seashore. And if she sells her shells by the seashore I'm sure, that the shells she sells are seashoreshells.
What noise annoys an oyster? Any noise annoys an oyster, but a noisy noise annoys an oyster most .
I even have a French one:
Ça chasseures chasser sans sont chien. (Those hunters are hunting without their dog.)
And I'll throw in a couple of Japanese ones too:
トラをとるならトラをとるよりとりをとれ、とりはおとりにトラをとれ。(Instead of catching the tiger, catch a.bird and use the bird as bait to catch the tiger.)
このたけがきにたけたてかけたのはたけたてかけかったから、たけたてかけた。(I laid this bamboo againts the bamboo fence, because I wanted to lay bamboo against it.)
Tres tristes tigres comían trigo en un trigal (three sad tigers ate wheat in a wheat field)
Pablito clavó un clavito, qué clavito clavó Pablito? (Pablito - short form of Pablo which would be Paul in English - nailed a little nail. Which little nail did Pablito nail?)
"Stekt torsk, kokt torsk" rapidly, meaning "Fried cod, boiled cod" and if you flub your tongue you sound like "Fried cod, boil idiot/dummy".
"Ibsens ripsbærbusker og andre buskvekster" meaning "Ibsens currant bushes and other bush fruits". That last part when flubbed sounds like "and other pant growths".
I just have to add one more, though it's not a tongue twister in the common sense, but it's too good to not mention it.
I found out meanwhile that there's even a rap version of this tongue twister! (I found out about it because there was a report in the news about two nuns going viral with their dance to this song.)
