The action you want to take when someone is very uneducated and doesn’t think.
“You know cami?” “The girl that faked her pregnancy?” “She’s so stupid.” “Think brain think!”
When you know somebody that is so stupid you just want to hit them on the head to get their brain going.
I swear when I heard what cameo did I just wanted to her her in the head and shout think brain think at her.
