OMO

On my own

Used to reference having to do something or go somewhere by yourself.

(slacker friend): "dude, totally just got the over achiever as my partner for the history project."
(you): "yeah there wasn't anyone left in my class so looks like I am OMO again..."

Or

(you): "dude Chelsea just asked duke to the dance!"
(best friend): "that sucks! Guess your goin OMO again."
