[This makes me mad!]

GRR

Think of the sound a cartoon bear might make when annoyed or frustrated. It’s short, guttural, and often spelled with repeated letters.

The clue "[This makes me mad!]" is a playful way to hint at the sound someone might make when annoyed or angry. "GRR" is a common onomatopoeic expression for a growl or frustrated noise, like what a person (or even a cartoon character) might say when irritated. The brackets and exclamation mark add emphasis, signaling the answer is a short, punchy reaction rather than a literal word. Think of it as the sound version of rolling your eyes or clenching your fists.
