What Does XX Mean?

XX means "two kisses."

Just like the letter X is used at the end of messages to represent a kiss, XX is used to signify two kisses. It can be typed in either uppercase (XX) or lowercase (xx) without significantly altering its meaning. However, uppercase may sometimes be used to provide emphasis (i.e., to signify a big kiss).

You should not necessarily consider XX as a sign of strong affection. Here is a table showing the possible meanings of Xs at the end of a message:
Number of XsMeaning
No X(1) If the sender normally sends an X, then the sender may be annoyed.
(2) If the message is business-like and not among friends, then no X is appropriate.
(3) If messaging is back and forth, then Xs are often dropped until the last message.
One X (1) A light kiss.
(2) If a kiss seems inappropriate, then the X probably just signifies a friendly tone. This unclear distinction does allow a single X to be used for flirting, as it provides the sender with plausible deniability. ("I was just being friendly.")
Two Xs With XX, the sender's intent was to send kisses.
Three or more Xs If you've been sent three or more Xs, they are definitely affectionate kisses. (See also XXXX.)

An Academic Look at XX

Back in the Middle Ages, a lot of people were illiterate and could only manage to write an X, which also represented the Christian cross. As a result, many people signed letters and sealed envelopes with an X, which they then kissed as a sign of faith and honesty.

It is also believed that an X represents the symbol for Christ, deriving from ΧΡΙΣΤΟΣ (the Greek word for Christ).

If the X represents a cross, it would be classified as a symbol, rather than a letter. However, if it represents the name of Jesus Christ, it would be a letter, in which case it would be an initialism abbreviation.
