"Ayy" is an expression of greeting, most likely coming from the word "hey". It is mostly used in ghetto culture, or by people high on marijuana, and can also be used as an insult or mockery.

1. A gentle 'ayy' symbolises gratitude among friends, and is often used as a general greeting

2. A more agressive 'AAAYYYYYYYY', is used to show anger amongst a close group of friends or family.

1. when said in a calm, appreciative tone, “ayy” means thank you.
2. when said in a high pitched, loud way, “ayy” means that you got fouled on your way to the hoop.
3. when said in a loud but deep voice, “ayy” can be used as a celebration, or, as a background for a rap song.
1. *friend passes blunt* you: “ayy
2. *sibling pinches you* you: “Ayyy!”

Ayi is a beautiful person. She is mistaken for shy, but when you get to know her she is very fun. Ayi is very talented and isn't afraid to show it. She values her friendships and would do anything for her friends. She has no time for boys or drama. You would be very lucky to have a friend like Ayi!
Wow...I would really love to hang with Ayi.
