What is Tasser (or cul tassé) in the gay french bareback slang and vocabulary?
“Tasser” or “se faire tasser le cul” (literally “to pack” or “to get one’s ass packed”) is a bareback vocabulary expression that describes the act of penetrating an anus already filled with semen. This rather vivid expression indicates that one will simply push the already present “juice” even deeper into the ass. “Tassage” (packing) is therefore often practiced by several people, when the passive partner has already received a dose of cum in their ass and one or more other partners immediately follow with penetrations, often cumming again (and without the passive partner “spitting out” the semen between each penetration from the active partners). It’s somewhat the pinnacle of the “plans jus” (juice plans) fantasy: having the maximum amount of semen in the ass, like a “cuve à jus” (juice tank)!
In what contexts is “tassage” practiced?
“Tassage” is a common practice in group sexual encounters. A passive partner receives a first ejaculation, and one or more other partners follow with penetrations without the semen being expelled in between. This is a way to accumulate a large quantity of semen in the anus, a central fantasy for those who enjoy “cuves à jus” (juice tanks).
The idea of “tasser” is directly linked to semen fetishism (spermo-fetishism). The more there is, the greater the pleasure for enthusiasts. The term implies a search for saturation and abundance.
“Tassage au jus” (juice packing) can also refer to the mouth: “bonne gueule à tasser” (good mouth to pack) is a term that can be found in ads. In any case, as the barebacker is a huge fan of “juice,” pushing their love of semen to fetishism for some, the more there is, the happier they will be, especially with multiple partners.
This term is therefore quite common when someone arranges a group sex session, goes to a cruising spot, or organizes a gang bang. Since the quantity of cum is what matters to them, they will necessarily need several juicy cocks or some very good cummers.
What does “Tu viens me tasser” mean?
Removing the notion of quantity, this term can simply mean that the person with the cum-filled ass has just had a sexual encounter where they were “dosed” just before talking to you: “Tu viens me tasser” (Are you coming to pack me?) would mean that someone has already been there and they haven’t expelled the semen, keeping it as a natural lubricant… A warning to those who like to wade in the juice!
