bababushka
If you’re a bababushka, you’re so brain-dead you think your mom is a lesbian and also think your math teacher is a robot. No one can argue with you because you’re too dumb to listen.
My brother said I was a bababushka because I thought the sun was a giant flashlight.
My friend called me a bababushka after I said the Earth was flat and made of candy.
In a group chat, someone said, 'You’re a bababushka, I give up.'
