One day Tadashi walks into his bedroom and realizes, "I'm a swag meister."
~
The next week when he walks into his bedroom, he has his hat on backwards, wearing red hater shades (like the blind ones except it spells HATERS GONNA HATE), money sign bling, and an inside-out shirt. Then he throws money everywhere. Hiro stares at him.

"What. The. Fuck?!" Hiro exclaims.

"I'm a swag meister, little bro," he responds. Tadashi flashes Hiro a gang sign and leaves.

The next day Hiro asks, "Where the hell did you get all that money?"

"I get it from all the ladies!" He moon walks out of the room while playing explosion sound effects on his phone.

The next day Tadashi wears extremely baggy pants. He jumps onto the swivel chair to go on the computer. It spins and Tadashi attempts to stop it infront of the computer, but the chair just keeps spinning. Hiro just stares at his older brother being stupid for once.

"Unbelievable," Hiro mutters. "What is wrong with my brother?"

"We shall never speak of this week ever again," Tadashi tells Hiro, back to normal.

"Agreed."

[Note: Not a x reader thing, but I really wanted to write it down. My friends came up with most of this. This is probably the best thing I've ever written. I'm gonna assume that this took place in summer... Pic from gakumi on deviantart]
