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!"
