The first "real" number in mathematics. Also seen in large quantities in posts by authors who have forgotten to hold down the "Shift" key.

The number you accidentally type when you try to type exclamation marks and accidentally let go of Shift too early.

Person 1: “Omg!!!1”
Person 2: “you typed a 1 at the end”
Person 1: “Dammit”

Why in the living fuck did you search for '1' on Urban Dictionary? Did you have nothing else to do? Did you search up something inappropriate and your parent/guardian walked in? Either way I think it's pretty weird.

Wtf i can't believe you just searched for '1' on urban dictionary
