Avoid marrying both your paternal aunt and your maternal aunt at once or any combination thereof.

This hadith is about marriage, specifically the combination of paternal and maternal aunts. According to this hadith, narrated by Abdullah ibn Abbas, the Prophet (ﷺ) abhors such combinations. This means that it is not permissible for someone to marry both their paternal aunt and their maternal aunt at the same time. It also implies that it is not permissible for someone to marry two paternal aunts or two maternal aunts at once either. The Prophet's abhorrence of this practice suggests that it should be avoided as much as possible in order to maintain proper family relations between relatives.
