- pertains to Sunny and Tiffany from Korean girl-group Girls' Generation, both their names end on "ny" thus "2ny"
- the so called "official couple" as defined by Girls' Generation's Tiffany, pertaining to herself and Sunny
- Girls' Generation's intimate and sweetest couple, for they have the most skinship in the group
I ship 2ny, they're the sweetest tandem in Girls' Generation.
I can't stop watching Sunny and Tiffany (aka 2ny), they're so cute and sexy together!
