Get past someone

The phrase may mean to get beyond someone's influence or vigilance.

Such as: "I just couldn't get past thinking about my former girlfriend (sad memories of the relationship)."

or ....

"I couldn't get past my boss prying eyes when I was napping at my desk."

Can you provide some context of how you see that phrase being used?

Alternatively, when I googled that phrase, I came up with this link:

get past (someone or something)

1. to move around or ahead of someone or something that is in the way. We have to get past the cart that is blocking the hallway. We just couldn't get past.
2. to pass ahead of someone or something that is moving. I want to get past this truck, then we can get into the right lane. When we get past, I'll stop and let you drive."

Those are all good, Ragman, but I'll bet Paolo is talking about fooling someone, as in, to put one over on someone.

"No matter how we tried, we couldn't get anything past Grampa."

"If you think for one minute that you are going to be able to get this fake invoice past Ed in Accounting, you are crazier than I thought."

Joe(is this the right track, Paolo.??)Nation

He has created another thread that he just started where he talks about one vehicle passing another.

He couldn't get that one past us.

What does "He couldn't get that one past us" mean in this case?

If you're referring to my comment, it was meant as humor --- a play on words.

However, it seems that you changed the question, so...:

To get one past ... means to sneak something by someone or to trick someone in order to purposely deceive them.
