AA Cup

The smallest bra cup size, mostly training bras but some AA cup bras and pushup bras are made for unfortunate adult women with AA cups

"Your AA cup bra is so small!"

"I still wear a AA cup, I can fit into all my training bras"

"Sorry, we don't sell AA cups here, have you tried gap kids? I heard they have a good training bra selection"

AA

Mostly in Roblox, but can be used in pretty much any game that has admins. AA stands for Admin Abuse, and is used when admins abuse their power. Admin abuse happens when the owner of a game gives an irresponsible person admin, or when they include a game pass that comes with admin abilities.

*admin gives everyone flying abilities and bans every admin in the server*
"Omg that is AA!"

aa

Often confused with people saying aa in terror instead of screaming in terror this word is saying: A form of lava that forms very rough and jagged. So unless you are screaming remember aa means a form of jagged lava, not your scared.

The aa sat still as I stared at it.
