When a lady is "entertaining" three gentlemen at the same time, ie taking it from behind, giving a blow job and having sex in the traditional manner. As all three orifices are filled, she has an "air-tight" seal, leading to the term Tupperware. I thank you.
Gary, Tom and Greg gave Sharon a Tupperware last night, she didn't know which way she was coming!
