g-argh-bbledygook!
argh is the sound a pirate makes when they’re mad and their ship is sinking. it’s also what your dog says when you steal their sandwich.
The pirate screamed, 'Arggh! My ship is on fire!' while the rest of the crew laughed.
My dog barked, 'Arggh! Why did you take my sandwich?!!'
I said, 'Arggh! This math problem is killing me!' during the test.
