When you have something weird af or private in your copy and paste, you type "123" and then copy and paste it exactly 3 times to make sure that weird shit is out of your copy and paste

person 1: Bro, I had a picture of my credit card, and I almost pasted it 'nstead of that cute dog photo! Luckily, I 123123123'ed it.
Person 2: Same! I had some rowdy shit in my copy and paste and did that.
