There’s a scene in “Call Me by Your Name” that I can’t get out of my head. (No, not that one.) It happens near the beginning of Luca Guadagnino’s gay odyssey, when Armie Hammer’s character, Oliver, sweaty from volleyball, pauses to steal a drink from Elio, played by Timothée Chalamet. Sensing Elio’s nervousness, Oliver begins to massage his shoulder. This is memorable not because we’re watching two straight actors perform a pas de deux of muted gay desire, but rather because of their difference in size. Hammer, 31, is 6-foot-5, with broad shoulders and body hair. Chalamet, 22, is five inches shorter, naturally smooth, with a pronounced clavicle and a concave torso. By gay male standards, he’s the ultimate twink.

Although the origin of the term has been disputed — some trace its history to “twank,” 1920s British slang for a client of gay male prostitutes, while others insist it’s a vulgar riff on the cream-filled Hostess snack — twinks are young, attractive, hairless, slim men. There are several modern variations: Euro twinks (the boys of BelAmi, a Slovak pornography studio named after the novel by Guy de Maupassant), twunks (a portmanteau with hunk, embodied by modern-day Zac Efron) and femme twinks (like the fabulous American figure skater Adam Rippon).

But the latest twinks — many of whom are straight — are what you might call “art twinks,” building upon an aesthetic legacy established by Ryan McGinley’s turn-of-the-millennium photographs of the sloppily skinny, or last decade’s leather-pant-clad Saint Laurent models chosen by the designer Hedi Slimane. And yet they are more culturally mainstream: a growing cohort of famous (and famously small) boys who stand in opposition to the lumbering, abusive oafs who have been dominating this year’s headlines.

Consider, for example, Tye Sheridan, the 21-year-old lead in “Ready Player One” — and one of few action heroes who won’t be busting out of his T-shirt anytime soon. Or the rising star Lucas Hedges, also 21, whose acting exudes anti-alpha softness. Christopher Nolan’s 2017 WWII epic “Dunkirk” was an ensemble showpiece of British twinkiness; “Love, Simon,” starring Nick Robinson, 23, is the American suburban version.
