Dicen is a new slang word used in 2018 or somewhere in the 2000's. It means that when your doing good at something or going fast, your dicen. It's kinda like saying "I was shredding on my dirtbike" so in other words it's a synonym for shredding.

A Spanish term, roughly translating to “many say that” used by Don Pollo during his TikToks. Sadly he is always interrupted before he gets to say anything.
Don Pollo: “Mucho dicen di que (roughly: many say that)” *the notifications begin* “anda pal Diablo” (roughly: go to hell)
