!!11oneone 

When someone on the internet gets really excited and wishes to put many exclamation marks, they sometimes let go of shift before the number 1, making their comment !!!!!!!!111. This practice has evolved to where people now put the written word "one" on the end creating this: !!!!111oneone

guy 1: did you hear? halo 4 is coming out!
guy 2: really?!?! i HAFTA have it!!11oneone

Used to show extreme exclamation. On most keyboards, the '!' exclamation mark is the shift function of the '1' key.

Often, when typing many exclamation marks, some 1's would appear as a result of continuing to hit the '1' key after no longer pressing Shift. The result would look something like this: !!!111. This has morphed into the use of "!!!111oneone" to show extreme exclamation.

Holy !@#% this site is AWESOME!!!!111oneone.
