2 Questions for good Spanish skilled

Question

"but before you rush in there" is translated to "Pero antes de que te entre la prisa"

There's no such thing as 'entrarse', right? and what does 'entrar la prisa' mean?

Answer 1

'entrar la prisa'

I have never heard it this way; normally we say "entar a prisa" ..... "enter quickly".

There is no "entrarse" but there are some slang terms using "entrarle" . Slang doesn´t have to be proper.
