bottles
"Bottles" has two main uses in English — it can be a noun (the plural of "bottle") or a verb (the third-person singular form of "to bottle"). Both are common in everyday life.
In everyday English, people often say someone 'bottles up' their emotions when they keep their feelings hidden inside instead of expressing them. The image is of trapping something inside a sealed bottle. You will often hear this as 'bottles up' rather than 'bottles' alone.
