Eric Dane's days as McSteamy might be well behind him, but he's still wowing fans with his charms... and a series of explicit scenes in 'Euphoria'.

The 'Grey's Anatomy' actor is among the stars of the critically acclaimed HBO series alongside Zendaya, Hunter Schafer, Jacob Elordi, Maude Apatow, and Sydney Sweeney. Following the last episode, Dane started trended on Twitter for a very NSFW moment.

Fans of 'Euphoria' made "Mark Sloan" trend on Twitter following a quite explicit intimate scene in one of the series' latest episodes.

Dane plays Cal Jacobs on the show, the strict father of Elordi's Nate. But Cal has a secret life: he has frequent hookups predominantly with young, queer men and trans women.

In episode two of the second season, titled "Out Of Touch," Cal has sex with a man and things get quite... McSteamy. Fans were so surprised to see Dane in an explicit oral sex scene to make the actor trend on Twitter.

"mark sloan putting the anatomy in grey’s," one person commented on Twitter, alongside a still from the series we can't really repost for obvious reasons.

"i have to keep telling myself that mark sloan and cal jacobs are two different people," was another comment.

"Now how did this show turn from Rue doing drugs to Mark Sloan eating *ss on television," another amused fan wrote

"Ayo they got mark Sloan eating ass on television! Lexi grey rolling over In her grave," one tweet reads.

"this show is so great cause it has dr. mark sloan eating butt. now that's mcsteamy," was another comment.

Other, very impressionable fans were shocked to discover why Dane was trending.

"i went to see why mark sloan was trending and i-," a fan captioned an 'iCarly' GIF of the protagonist getting blinded.

Zendaya Shares Important Reminder For 'Euphoria' Fans

Debuted on HBO on January 9, the second series of 'Euphoria' has received positive reviews.

Ahead of the premiere, Zendaya shared an important reminder for fans of the show.

The 'Spider-Man: No Way Home' star, who plays protagonist Rue Bennett in the series by Sam Levinson, took to her social channels to warn viewers against some potentially sensitive content.

"I know i’ve said this before, but I do want to reiterate to everyone that 'Euphoria' is for mature audiences," the actress wrote on Twitter.

"This season, maybe even more so than the last, is deeply emotional and deals with subject matter that can be triggering and difficult to watch," she added.

She continued: "Please only watch it if you feel comfortable. Take care of yourself and know that either way you are still loved and I can still feel your support."
