OLS
n.— «Raise the leg of your choice right in front of you, six inches off the ground, leg straight, toe pointed. Keep your eyes on your raised toe and begin counting aloud from 1,001 until I say stop.…This is the one-leg stand—OLS in cop-speak.» —“DUI Hokeypokey” by Brigid Schulte Washington Post Nov. 15, 2005.
