Validate Lowercase Underscore Sequence

Write a function `text_lowercase_underscore` that checks if a given string contains sequences of lowercase letters joined by an underscore (`_`). The function should return `True` if the string matches this pattern and `False` otherwise.

#### Example Usage
```python [main.nopy]
text_lowercase_underscore("aab_cbbbc")  # True
text_lowercase_underscore("aab_Abbbc")  # False
text_lowercase_underscore("Aaab_abbbc")  # False
```
import re

def text_lowercase_underscore(text):
    """
    Check if the input string contains sequences of lowercase letters joined by an underscore.

    Args:
        text (str): The input string to check.

    Returns:
        bool: True if the string matches the pattern, False otherwise.
