latching on
n.— «Linda Parker, the instructor, shimmies to the right and then to the left, her tan, pointy cowboy boots gliding across the carpet. Her thumbs are tucked into her black belt, a practice called “latching on.” “The reason you do that is to keep your body centered, to keep you from tipping,” the Madison Heights resident says after class.» —“These boots were made for dancing” by Casey Gillis News & Advance (Lynchburg, Virginia) June 2, 2008.
