Any random languages you make up for fun are technically Gibberish because they aren't official languages.
I have two examples of Gibberish, which mean "I love you so much" in English:
- Tuk lamobez na'zi aytam (pronounced too-kh law-moh-behz nah-see ay-tawm)
- Ego tela mikari amapes (pronounced eh-go teh-lah mee-kaw-ree ah-maw-pays)
