How to Say "mates" in Spanish

The Mixed-Group Rule
In Spanish, if a group of friends includes even one male person, you must use the masculine plural form 'amigos'. The word 'amigas' is only for groups of all females.
Forgetting the Mixed-Group Rule
Mistake: “Seeing a group of five women and one man and saying 'mis amigas'.”
Correction: Always use 'mis amigos' for a mixed-gender group. Think of the '-o' ending as the default for groups unless you're 100% sure everyone is female.
