Well, I can think of 3 phrases:

1. How to say tie your shoelaces in Spanish or How to say your shoelaces are untied in Spanish
2. How to say close your zipper in Spanish
3. How to say you have a booger in your nose

How to say tie your shoelaces in Spanish

Átate los cordones (de los zapatos).
Tie your shoe laces.

I have also heard Spanish speakers say:

Amárrate los cordones (de los zapatos).
Tie your shoe laces.

Both “atar” and “amarrar” mean the English verb “to tie.” And “cordones” means the English word “laces.”

And How to say your shoelaces are untied in Spanish:

Tus cordones están sueltos/desatados

How to say close your zipper in Spanish

Súbete el cierre.
Close your zipper.

A closer translation for “súbete el cierre” would be lift up or raise your zipper.

Besides the phrase “súbete el cierre” you may also hear Spanish speakers say:

Súbete la cremallera.
Close your zipper.

I have heard both phrases used in Colombia. And when preparing this email, I telephoned a Dominican friend who has lived in Spain for just as long as I have lived in Colombia, and she told me that in Spain they often use the word “cremallera” (zipper).

But in both Spain and Colombia, “cremallera” is considered a more formal way to say zipper.

By the way, I didn’t bother to ask my Dominican friend how would Dominicans say “close your zipper.” She had lived in Nueva York for over 10 years before moving to Spain. And I am absolutely sure that if I had asked her that question what she would have told me is the way Spanish speakers in New York and the other parts of the U.S. say the phrase.

And the phrase that I have always heard ALL SPANISH SPEAKERS in Nueva York (New York) say is:

Súbete el siper (zipper).

I am not sure if the word “siper” (zipper) is a word from the Spanish language or the “Spanglish” language.

By the way, I remember an interesting question that a Mexican friend in Nueva York asked me when he was studying English:

He asked me why do Americans say “your fly is open” when they want to say “tienes el cierre abierto.”

Or as they would say in Colombia when speaking formally:

Tienes la cremallera abierta.
Your zipper is open.

How To Say You Have a Booger in Your Nose In Spanish

The third and final phrase for today, you may want to skip if you easily find things “asqueroso” (disgusting). And that’s how to say, you have a booger in your nose in Spanish:

Tienes un moco en la nariz.

Notice that in Spanish the phrase “en la nariz” is used instead of “en tu nariz.” It is implied that YOU have it in YOUR nose — and not in the nose of someone else.
