Justin Bieber Twitter orgasm joke: Selena Gomez's ex promotes new song 'Hold Tight' with sexual reference to 'When Harry Met Sally' [VIDEO]

Rumors suggest that Justin Bieber totally disses Selena Gomez's BFF Taylor Swift in his new hit single "All Bad." But apparently, the 19-year-old pop star would rather talk about sex in his song "Hold Tight" rather than ex-girlfriend drama...

On Friday (Nov. 15), the Biebs posted this rather suggestive Vine video on Twitter:

@justinbieber: "Hold tight. Lol."

Holdtight#justinbieber #beliebers #comedy #harrymetsally

Is the "Heartbreaker" crooner referencing... orgasms? Beliebers are probably riled-up right about now!

Hmm... wonder if the Biebs had an interesting night?

The short clip features the famous "restaurant orgasm" scene from the popular 1989 rom-com "When Harry Met Sally" -

Then Bieber cuts to a scene from his "As Long As You Love Me" music video where he's making out with some hot brunette:

Do Mstars fans think the video's funny, or just weird?

And here's the release of "Hold Tight" -
