gafaga haga - A vagina so bad it turns people into babbling fools who can'

A vagina so bad it turns people into babbling fools who can't even form a complete sentence.

I looked at it and said, 'Why is my brain melting?'

My friend saw it and started talking like a robot. 'Beep. Boop. Gafaga Haga.'

I was so confused I asked, 'Is that a vagina or a portal to hell?'
