jaantje
A person who talks too much and doesn't shut up. She's annoying and doesn't know when to stop. She's loud and won't let you finish your sentences. She's a pain in the ass and won't leave you alone.
Jaantje talked for 10 minutes about her cat. I wanted to scream.
She interrupted my whole speech. I died inside.
She wouldn't stop talking even when I said 'please shut up.'
