1. Quantile-quantile (plot)
Units & Measurements · Statistics Abbreviations
A graph that plots the quantiles of a data set against those of a theoretical distribution, usually the normal. Points along a straight line indicate the data follow that distribution.
Example: The QQ plot of residuals bends upward at both ends, suggesting heavy tails.
Also written Q-Q. Curvature at the ends reveals skewness or heavy tails, while an S-shape indicates tails lighter or heavier than normal. Regression diagnostics in R include a normal QQ plot by default, and two samples can also be compared directly against each other.
2. Crying (emoticon)
Texting & Internet Slang · Gaming Slang Abbreviations
Mocking reaction to someone complaining, whining or losing, as in "QQ more." The two Q's resemble a pair of eyes with tears running down.
Example: Lost one match and he's already QQing in all chat.
Dates to early-2000s online games such as Warcraft III and World of Warcraft, where "QQ" and "QQ more" became standard trash talk. It also appears as a sad face in East Asian chat, and QQ is the name of a major Chinese messaging app run by Tencent, which context distinguishes. Usually condescending.
3. Quick question
Writing & Everyday · Email and Office Abbreviations
Opens a workplace chat or email with a brief question, signaling that only a short answer is needed. It is common in Slack and Teams messages.
Example: QQ: is the client call at 3 or 3:30 your time?
In gaming slang, QQ represents a pair of crying eyes and means complaining, a different and older usage. In the workplace sense it is typically followed by a colon and the question itself. Chat etiquette favors putting the full question in the first message rather than sending a bare greeting and waiting.
