O-Face 

In 2010, Thomas' aghast face, also known as the infamous "O" face, when the Fat Controller asks the inspector if he saw fish, along with the musical note that went with the shot, became an internet meme.

Person 1: I hate Thomas the tank engine
Person 2: why
Person 1: because the O-Face scares me

O.B.B. 

OBB stands for Ooga Booga Bullshit. When 'people' get mad they 'chimp out' thus making the ooga booga sound, similar to a gorilla, then carry-on with bullshit. Usually senseless violence accompanied with 'angry noises'.

Person A sees person B starting to 'chimp out' in their general direction.

Person A says "Keep that O.B.B. away from me!"

Person B *Carries on in a different direction*

Person C *receives O.B.B. instead of Person A*

Person of Irish decent. Politically active. Drinks and Bullshits. Rarely fights unless fighting the English. Amazing lovers.

The best lover I ever had went by the name O'Leary

O'Leary is drunk and bullshitting about politics again.
