I have a t-shirt with this

Question

"Mucho me diran aventuro,y lo soy, solo de un tipo diferente ponen el pellejo para demonstrar sus verdadas."

Answer 1

I have a book with a phrase from el Che Guevara, which is quite similar to yours. It says:

Muchos me dirán aventurero, y lo soy, sólo que de un tipo diferente y de los que ponen el pellejo para demostrar sus verdades

Many will call me an adventurer — and that I am, only that one of a different sort: one of those who risks his guts to prove his truths

Answer 2

If you're quoting exactly, I'm afraid it's not really correct Spanish, and it doesn't quite make sense.

Answer 3

very funny t-shirt but i do not exactly know what it says, i'm sorry!
