I struggle with the following:
I have an input list:

```py
input_list = [
    "Beneficiile pozitive ale productName:",
    "Care sunt ingredientele product name?",
    "Ce este product name ddd?",
    "Ce face product name decât orice altă îngrijire a pielii?",
    "Cum funcționează?",
    "product name pret – Ia Piele Tineresc Natural! Pareri, Cumpăra",
    "Offer Nutra",
    "Offering Top Nutritional",
    "În cazul în care pentru a cumpara Crema product name?",
]

```

I need to count each list item and get a most frequent phrase or word from the whole list of items.

There are some answers here where I can count words but in that case I need a two-words phrase to be returned

Expected output:

In this case the returned output should be 'product name' because it occurs in 5 list items in this case.

Again - I don't want to count words but phrases which occurs multiple times in list items.
