The Fighting Irish is a sex move in which one replicates the stereotypical, yet beloved, view of a fighting, green clad, shamrock wearing, Irishman/leprechaun by vigorously and erratically punching one's fists into a woman's vagina and anus until orgasm is achieved.
"I gave this chick The Fighting Irish the other day..."

"The Fighting Irish?"

"Yeah, you know."

Takes an old timey boxers stance, with both fists held in front and begins to punch.

"One in the pink! One in the stink!"

Refers to when the supreme alpha male in your school receives a full-ride scholarship to the University of Notre Dame. One might confuse them with an Irish teacher with the last name Wilson, but to differentiate, the supreme alpha male will fist both the asshole and the pussy, not just the pussy. Likewise, when referring to one as a Fighting Irish, he must be excellent at destroying beds in bedwars.
Jwil: Did you see that kid who got the full ride to University of Notre Dame?

Dwil: Yes, I did.

Jwil: Now he thinks he's more Irish than us. This is just not okay.

Dwil: Damnit! Now we cannot seduce anymore women because of his bedwars abilities and his Irish jig dance.

Jwil: Although he has take our potatoes, I cannot help but admire what a Fighting Irish he is.

A legendary player in the game Regnum-Online, both for his skill and the fact that no matter what is asked his standard answer is "I can't be arsed"
In a sense Fighting Irish is both used as a derogatory name AND as a positive label of empowerment.
Hey dude, can you help me?
- I can't be arsed
Quit being Fighting Irish.

Wow, did you see that guy kill 5 players in a row?
- Yeah, that's Fighting Irish

The most recognized football fight song in the nation without any debates. Often played for the University of Notre Dame's football team, which is often referred as the most storied football program in the nation.
I hate Notre Dame, but the Irish fight song is money.
