Shit Flash Avatar Chat
shit-topped graphical chat ("online hangout").
Refers to Gaia Online, Club Penguin, Pixie Hollow and other such things.
Girl: Mom, can I log to Club Penguin for 15 minutes?
Mom: Nope! You will no longer waste your time on those...
Dad: Graphical chats are bad!
Boy: Yea! Block access to all those SFAC's!
Dad: What does that refer to?
Boy: Stupid Flash Avatar Chat.
Dad: Did you mean, "Shit Flash Avatar Chat"?
Boy: Pretty much!
