To have a neck and neck insanely close game of Fifa/Pro evo but wait until the very last min to score the winning goal and win the game.

'Ahhh you fucker! You O'Neilled me!!'

O'Neiller 

An O'Neiller is when someone is on the down and out in some shape or form, and decides to grow a beard and lets their Appearence Dishevel. It often occurs in men between the ages of 27-40, It is not to be Mistaken with mid life crisis. O'Neillers are bred from hatred and often the lack of Sexual Intercourse.

Folklore tells us that the Famous O'Neill was Roland Turlogh O'Neill, a feared Celtic warrior from Carlow town who was also said to have been a fantastic painter/decorator and a very Agressive Bearded lover.

After Patsy left him, Joe went on a terrible O'Neiller.
