Sexual innuendo is present throughout the film.
The title is a reference to a term that seedy spas use for post-massage sexual favors (the three leads being masseuses), but it is actually a reference to the three leads being spies (akin to Kingsman: The Secret Service).
Multiple scenes of men being shirtless.
A man is stripped to his boxers during a fight scene (played for comedic purposes).
Female cleavage is present in almost every scene in the film.
Early in the movie, a man reveals himself to be a messenger from the ladies' bosses, and is asked for the brief (the briefing). The information is presented in an actual green brief underwear.
Gie looks aat the two pearls they have, and the shot aligns the two pearls with Larry's crotch. Gie comments, "They're so big! Amazing! Just wait until there's three of them." Lolly, who is unaware of the pearls or the girls' other job, overhears this, thinks out loud, "Three? Aren't there only two of them?"
Moe, Au's ex, makes advances on Au and takes off his shirt to seduce her. Au leaves, but is clearly attracted to Moe.
Au sees Em and Carlo in bed. Em has a blanket wrapped around her, but we see Carlo wearing only his underwear. Au makes a comment about Carlo's body, and we think she's about to say something about his crotch, but she says "hard biceps."
