freeball
 v.— «Call it free-balling, California casual, alfresco, or the much-preferred “going commando.” Unless that sundress is super susceptible to breeze, super short, or you’re super drunk, no one will know the difference.» —“Uncle Sam’s men think undies aren’t necessary; why should civilians?” by Rebekah Gleaves Memphis Flyer (Tenn.) June 26, 2002.
