look up any word, like bangarang:
 
11.
A situation during intercourse in which a woman involved in an orgy with two men has one man penetrating her from the front while the other man penetrates her from the back. This can also happen with two women, in which both women are wearing strap ons, penetrating the targeted woman from both the front and back. It can also happen with a man, and a woman wearing a strap on.
The three lesbians were making out naked, when two of them put on strap ons and gave the remaining lesbian a two way. It gave her an instagasm.

short for two-way pager- a small electronic device that allows communication in two directions; a more advanced version of the original "pager" which worked by allowing a caller to send a numeric message to the person with the pager. After this message, the person would have to find a telephone to place a return call. A two-way pager allows a message (text) to be returned to the person placing the original page.
