Y'all on™ is a way of asking if someone is on or announcing that you yourself are on Xbox, while also making fun of Aeden Shimada.

Y'all in™ is another term derived from y'all on™ in which Aeden Shimada approaches us at a bar and asks if we would like to be apart of a series of daring heists.
Us: "Aeden we're in a party wanna join us?"
Aeden Shimada: "Oh, Y'all on?"
Us: "...Are you farkin stupid?"

Southern 2nd person plural pronoun. Most concise and easily distinguished. Despite the assurance of some emails that have been passing around, "y'all" is plural. Only an absolute idiot would use it as a singular pronoun.
