ピアス

Etymology
From, misinterpreted as a gerund of.

Noun

 * 1) piercing (especially ear piercing)

Usage notes
This specifically refers to earrings which loop through the earlobe and require a piercing in the ear, and is the general term for earrings. The more similar-sounding is less commonly used and refers more specifically to earrings which do not require a piercing in the ear, by clipping to the earlobe rather than looping through it.
