AA

AA has 3 meanings
1. What does aa mean in League of Legends?

Autoattack

In League of Legends (LoL), "aa" stands for "auto attack" (also known as a "basic attack"), which is the default attack action performed by a champion when you right-click on an enemy unit. Auto attacks are a fundamental aspect of the game that deal consistent damage to opponents (as long as the enemy is within range) without requiring special abilities or resources.

LoL gamers often use auto attacks to harass enemy champions, farm minions, and secure kills during battles. They are especially helpful since they only require a click, allowing players to focus on movement or other abilities while still inflicting damage.

2. What does AA stand for in chat slang?

Adiós amigo

In chat slang, AA means "Adiós amigo," which is Spanish for "Goodbye friend." Friends might drop a quick AA into chat before they head out for the night, back into RL.

You can respond to someone who says AA with TTYL or l8r, but you better hurry! If you don't type quickly, your friend might already be AFK.

Example

L8r g8r!
AA! TTYL

Being able to say AA means you have a friend! Nice work!

3. What does AA stand for in forum posts?

As above

AA is shorthand you may see in online forums and chat rooms to help streamline conversations, allowing users to quickly refer back to something previously mentioned in a thread or chat. It signals "I've already mentioned this, check it out above!"

Likely, only Internet-savvy users will use AA since the shorthand is rather obscure. Instead of repeating themselves, they type "AA" to make sure others stay on the same page. Since AA eliminates redundant dialogue, it keeps online discussions, such as spirited debates or casual banter, organized and focused.

Example

hey, what did you say about the meeting time?
aa, check my last message. i mentioned it there!
