The "Δ)" emote or "That deltan" emote is a symbol used in online communities, particularly on Twitch and Discord, to represent the Greek letter delta followed by a closed parenthesis. It can be interpreted as a shorthand way of expressing "difference" or "change," often used to indicate a shift in mood or topic in a conversation. The emote is typically displayed as a small yellow triangle with a curved line representing the closed parenthesis.
