i'm 14 and this is deep
It's when some kid says 'I'm 14 and this is deep' just to act like they're really sad, but they're just being a pain and don't even understand it.
'I'm 14 and this is deep' after a post about being sad that had 3 likes.
'I'm 14 and this is deep' even though they just got a D on their homework.
'I'm 14 and this is deep' because they were wearing pajamas at 3 PM.
