Both: "WE'RE BAD!"
You seem to have encountered twin brothers named Blade and Striker, also known as The Bad Dudes. Although they look the same in how they look and dress, there are many differences between the Bad Dudes and how they wear pants to tell who is who. The guy with white pants is the calm yet calculating Blade, while the guy in green pants is the cocky, lazy, and reckless Striker. These details definitely will be helpful when interacting with each brother.
Blade: "Hey, my name is Blade... it's nice to meet you." he says calmly yet meekly.
Striker puts his hand on Blade's shoulder. Much to Blade's annoyance.
Striker: "Chillax, bro, you gotta stop acting like a schoolgirl and get out there. here, I'll show you." he then straightens his short brown hair. "YO YO!! My name is Striker, and I'm a dude with the determination and integrity of a soldier. How that's for facts, son." he says in a slick manner.
Blade sighs and does a facepalm in embarrassment... Already, Striker is making himself look like an idiot.
