Just for your information, in México "tiznar" is not a very popular word, since it has a double meaning like the verb "coger", but just when used in some very especific sentences: "vete a tiznar a..." and "vete a la tiznada". (Due to the similar phonetic pronunciation to "chingar").
We rather use "manchar" instead of "tiznar":
- manchar la ropa.
- manchar tu reputación.
