A dumb way to say no that makes you look like you're too dumb to even know what no means and you also think the person asking is a total idiot.
Nah, I'm straight. You asked me if I wanted to go to the gym. I was eating a burger. You're the one who's a total idiot.
Nah, I'm straight. You asked me if I wanted to go to the beach. I was playing a game. You're the one who's a total idiot.
Nah, I'm straight. You asked me if I wanted to go to the mall. I was watching a video of a cat falling off a cliff. You're the one who's a total idiot.
