Warning: it is really stupid.
In college, I lived in an on-campus apartment that was down a very short hill from the parking lot. I’m talking a barely perceptible slope across literally 5 feet.
For some reason, the school felt the need to put a tiny staircase leading from the parking lot to the apartment. I guess during the winter we appreciated that, but in good weather it was very apparent just how useless that staircase was.
Because the staircase served no purpose, my roomates and I had a house-rule that we would always deliberately walk on the hill next to the staircase, rather than actually use it.
One day, one of my roommates used the stairs as we were heading to her car to go to a dining hall or something.
Since this was against the house-rules, I said “Hey! Turn around right now, go back down those stairs, turn right, and go up the hill like a normal person!”
She replied “is it ok if I turn left instead?”, because this is exactly the kind of dumb joke that was typical for the two of us.
I thought about it for a moment, and said, “eh, I’ll accept it.”
I guess I used a bit of an accent when replying, because my friend responded with “did you just say Alex Eptit ?”
I laughed, and said “no, but I’m definitely using that for my next character/account name!”
(Again, because we do dumb stuff for even dumber reasons all the time)
A couple days later I bought Overwatch, and AlexEptit (I’ll accept it) was born.
Most players I encounter think my real name is Alex (one guy kicked me out of his LFG group because “anyone who uses their real name in OW is an idiot”. The irony was hilarious), and many of them struggle to figure out how to even pronounce it (Alexa Petite and Alec’s Epic Tit are both common guesses).
And I can count on one hand the number of people over the years who have realized it was a phrase rather than a name without any prompting from me.
