Glossary of Australian Threesome Slang and Terms

  • Threebie
    • Description: A playful Aussie-coined term for a threesome, blending "three" with a cheeky, casual vibe. Think, "We had a threebie last night—bloody wild!"
  • Ménage à Trois
    • Description: Borrowed from French but used in Australia with a posh or ironic twist, meaning a sexual encounter with three people. Often said with a wink, like, "Fancy a ménage à trois, mate?"
  • Throuple
    • Description: A term for a committed romantic trio, popular among poly Aussies. It's less about a one-off and more about ongoing love, e.g., "They're a proper throuple now, living in Bondi."
  • Spit Roast
    • Description: Crude Aussie slang for a threesome position where one person is penetrated from both ends (oral and vaginal/anal). Common in blokey banter, like, "Mate, we gave her a spit roast—she loved it."
  • Devil's Three-Way
    • Description: Slang for a threesome with two blokes and one sheila (woman), often implying a cheeky or taboo edge. "Heard they had a devil's three-way down at the pub."
  • Two Blokes and a Sheila
    • Description: A distinctly Australian twist on the MMF (male-male-female) threesome setup, leaning into local lingo. "It was two blokes and a sheila—fair go, everyone got a turn."
  • Sheila Sandwich
    • Description: A playful term for an FFM (female-female-male) threesome, with the bloke "sandwiched" between two women. "Caught him in a sheila sandwich—lucky bastard!"
  • Rooting Trifecta
    • Description: Aussie slang where "rooting" means sex, and "trifecta" (from horse racing) implies a winning trio. "We hit the rooting trifecta last weekend—bloody oath!"
  • Three's a Party
    • Description: A lighthearted Aussie spin on "three's a crowd," flipping it to celebrate a threesome. "Nah, mate, three's a party—bring it on!"
  • Unicorn
    • Description: A term used globally but big in Australia's poly scene for a single person (often a woman) who joins a couple for a threesome. "She's their unicorn—rare and bloody perfect."
  • Double Dip
    • Description: Casual slang for a threesome where one person gets attention from two others at once, like dipping into two treats. "He copped a double dip—smug prick."
  • Tag Team
    • Description: Borrowed from wrestling but used in Aussie slang for a threesome where partners take turns or work together. "We tag-teamed her—smooth as silk."
  • Poly Pash
    • Description: "Pash" is Aussie for a passionate kiss, so this means a three-way makeout session. "Started with a poly pash, then shit got real."
  • Full House
    • Description: A poker-inspired term for a threesome that's a "complete set"—everyone's involved, no one's left out. "We played a full house—everyone's a winner."
  • Randy Trio
    • Description: "Randy" means horny in Aussie slang, so this is a lusty threesome crew. "That randy trio was at it all night—fair dinkum."
  • Bikie Bash
    • Description: A rougher term (from "bikie," Aussie for biker) for a wild, no-rules threesome, often implying a gritty vibe. "They had a bikie bash down by the dunes."
  • Snag Fest
    • Description: "Snag" is slang for sausage (or penis), so this is a cheeky nod to an MMF threesome heavy on the male action. "Turned into a snag fest—top stuff!"
  • Love Triangle with Benefits
    • Description: A tongue-in-cheek way to describe a threesome that's more than just sex—some feelings sneak in. "It's a love triangle with benefits—messy but hot."
  • Triple J
    • Description: Inspired by the Aussie radio station Triple J, this is a youthful, fun term for a threesome with a laid-back vibe. "We pulled a Triple J after the gig—sweet as."
  • Fair Go Three-Way
    • Description: Rooted in the Aussie value of "fair go" (everyone gets a chance), this means a threesome where all parties get equal play. "Kept it a fair go three-way—no complaints!"
