obvious
It’s like when someone says something, and then adds, 'slash obvious.' You’re like, 'Why are you even talking about this? It’s like watching a baby walk.'
'This is the best plan ever,' slash obvious. 'You just said that? What's wrong with you?'
'He’s going to win,' slash obvious. 'He’s obviously going to win. Why are you even saying that?'
'That’s the most obvious thing I’ve ever heard,' slash obvious. 'So are you telling me you’re not a brain-dead moron?'
