There is absolutely no other definition for an o face besides the face a youtube viewer makes when he or she is craving an outro performed by Tobuscus.
Also known as "outro-jingle face," or "outro face"
I was totally having my o face on, and then he finally fufilled my needs.

Tobuscus: You had that outro-jingle look on your face - no offence. That's a compliment. A very attractive feature in a lot of cultures, called outro face - look it up! - or o face, for short.

originating from the movie Office Space, o-face describes the face one supposedly makes while ejaculating onto a woman, esp. the areola/nip of the left titty. yes my friends, that is the sweetspot. you know you've hit home when her left tittay is covered in skeet. she will love it so much, she will beg for a cleveland steamer to finish the charade off.
**sexual things take place**
man's voice: OHHHHH OHHHHH (while face is contorted with happiness)
**ejaculate spews**
