ピアス

From English piercing, misinterpreted as a gerund of pierce.

• IPA^(key): [pʲia̠sɨ̥]

ピアス • (piasu) 

1. piercing (especially ear piercing)

   ピアスをあける

   piasu o akeru

   to have a piercing done

   (literally, “to open a piercing”)

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 イヤリング (iyaringu) 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.
