Gacko
A person who’s so determined to be cool they’ll try to speak in a high-pitched voice and still get called out for it. They’re like a chicken who thinks it’s a superhero.
'He tried to speak like a robot and still got called a Gacko.'
'She tried to sound like a princess and ended up sounding like a parrot.'
'He tried to fit in by speaking in a high voice and still got called out.'
