toe-tapper
n.—Gloss: a homosexual. Note: This is a very new use of the term that references the arrest of Senator Larry Craig of Idaho for soliciting gay sex in a public bathroom in June 2007. In public bathrooms used as cruising joints, toe-tapping is a common way of letting others know that you’re there for a sexual liaison. «The photos on the site do not show the fellow’s face, but the profile does feature pictures of a toe-tapper posing naked in various positions, including full frontal.» —“New Sex Mess Jolts ‘Insider’” New York Post Sept. 7, 2007.
