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

Person 1: “Omg!!!1”

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
