Origin & Background
The use of X as a kiss has existed for centuries. Historians believe people who couldn’t write their names would sign documents with an X, then kiss the mark as a symbol of honesty and sincerity.
Over time, the tradition became associated with affection. As letters became popular, people ended them with one or more X’s to show warmth.
With texting and social media, this habit became even more common. Today, people frequently add x, xx, or xxx at the end of messages to sound friendlier.
Meanwhile, XX already had separate meanings in Roman numerals, genetics, mathematics, and medicine long before texting adopted it.
What Does XX Mean in Texting

It adds warmth, kindness, or affection without being overly romantic.
Friends, family members, partners, and even coworkers in some countries use it naturally.
Examples:

- “Sleep well xx”
- “Miss you xx”
The meaning depends on your relationship with the sender.
XX Meaning in Number
As a number, XX represents 20 in Roman numerals.
Roman numerals use letters instead of digits.
- X = 10

- XXX = 30
You’ll often see Roman numerals on:
- Clock faces
- Book chapters
- Sporting events
- Historical monuments
- Movie sequels
What Does XX Mean in Roman Numerals
Roman numerals use X to represent ten.
Since two X’s appear together:
X + X = XX = 20

This is one of the simplest Roman numeral combinations.
XX Meaning in Pregnancy
In pregnancy and genetics, XX usually refers to the female chromosome pattern.
Humans typically have:

Doctors may mention XX when discussing chromosome testing, prenatal screening, or genetic reports.
It does not predict personality or future traits—it simply identifies the typical chromosome combination.
XX Means Hugs
Although X traditionally means kisses, some people mistakenly believe it means hugs.
In most English-speaking countries:
- X = Kiss
- O = Hug
However, some families or friend groups use XX simply as a symbol of affection without distinguishing hugs and kisses.
The exact meaning depends on personal habits.
Meaning of XX in Scan
Medical scans and laboratory reports sometimes mention XX when discussing chromosome analysis.
Examples include:
- Prenatal screening

If a report states 46,XX, it generally indicates the typical female chromosome pattern.
Always ask a healthcare professional if you have questions about medical results.
XX Emoticon Meaning

Instead of sounding cold:
“Thanks.”
Someone might write:
“Thanks xx”
