Swearing on Miiverse is tuff as hëll

Didn't know how else to express such adrenaline and isn't the word "tuff" like old slang like from 70s-80s ish then the newer generations started using it idk its a genuine question not to updated on slang past gen-z. While im at it what does "67" mean?

tuff is a gen alpha slang (I mostly just say it ironically), also 67 is just a video of a kid saying six seven

and yeah id like to play mario kart with you, im pretty skilled

Thanks for educating me LoL!!! Whats your VR? Mine is 10000 but my other wiiu decided to kill itself (its nand fried) so now im slowly grinding my whay back im around 3200 ish currently. How about you?
