When someone knows you're jamming to your favorite tunes but still talks your head off like you're deaf and dumb.
'Hey, I know you're listening to music, but I need to tell you about my cat's new job!'
'I swear you can hear me, but you're just ignoring me like I'm not here!'
'You're wearing earbuds, and I'm still yelling at you like you're in the next room!'
