When speaking of one's Italian muscle, one often refers to the male genitalia also referred to as 'phallus'. Due to the Italian culture often being associated with romance and affection, and the penis being a prominent muscle, one's "Italian muscle" is a reference to one's penis.
"He really knows how to flex his Italian muscle"
"I could use some Italian muscle on Friday night"
Stairs that are too big to take one step and too small to take two steps between each stair. Usually the only stairs in Italy.

A particularly hot, gorge, VERY well endowed Italian Silver Fox, or foxy DILF, who can literally go for hours and hours and hours like the stallion he is, making a woman squeal over and over again in total ecstasy until she gets that high she can actually see into the future, around corners and into parallel dimensions. That takes some doing. High five foxy DILF stallion! Yee ha! :)
The Italian Stallion had sexy time with the MILF in Durkastan and made her feel like an entirely new, refreshed woman...
