The opposite of C++, the incredibly versatile programming language. X== is the single worst programming language, and requires lots of Alt codes to be entered on a near constant basis. (Most often Alt+0181 and Alt+21 in an annoyingly repeated fashion.)

X== was developed in the early 2000's by a currently unidentified programmer that wanted to annoy his friends, all of which were coincedentally allergic to beets.

Most X== programmers kill themselves after a short period of time, but have difficulty because of the near-immobility of their hands/wrists brought about by abnormally advanced stages of carpal tunnel syndrome.

*a few months pass*

Programmer: "What was I thinking?"

*Programmer kills himself*

You go to a forum and do a member lookup on x' OR 'x' = 'x
The mySQL query would look something like SELECT * from members WHERE user = x' OR 'x' = 'x'. This query, instead of returning the member "x" would return every member in the database. This isint useful, but in other cases it would be.

Get the )x( mug.
Pronounced as “ex.” The debatably new “terrible” or “terrifying” name for the formerly known Twitter app, which reminds billions of kids and their parents worldwide of their dreaded years-long school algebra.
Are the days of X numbered, especially when two key rivals are exploring whether or not they’d also be renaming some of their subsidiaries Y and Z to strategically create confusion and chaos on social media?
