1

(Definition A)
The 1337 way of noting that you must leave. As most people chatting online are lazy, they always look for shortened ways to convey their messages. In this way, the evolution of this term has inarguably reached its peak.

"Gotta go" -> "g2g" -> "g to g" -> "g/g" -> "1"

Thus, from idiom to abbreviation to mathematical ratio, we have 1.

(Definition B)
Again, along the lines of 1337, groups of 1s may be used to end exclamatory sentences, usually for the purpose of mocking n00bs who greatly overuse exclamation marks and fail to release the 1 key before the "Shift" key. May be used with extra extensions such as "one", "eleven", "sin(x)^2+cos(x)^2", or "-(e^(pi*i))". See the example for greater detail.

(Definition C)
For younger children, especially those recently potty-trained, a brief system of number codes is used to prevent embarrassment when a child audibly requests to use visit the restroom in public. Urination is referred to as "1", excrement is "2".
