Face Baggery
Going on a rage-filled rant about something you said you didn't care about, all while ignoring the facts and making things worse.
"I didn't care about this topic!", 30 minutes later, he had posted 12 replies and was screaming about how everyone was wrong.
"You said you didn't care about the math test? I saw you crying in the hallway.", and he still didn't get the question right.
"She said she didn't care about the fight. Then she texted me 10 times about it."
