A sexual act believed to originate in Wichita, Kansas during the 1940s. This act requires two women, a rusty metal pipe, soapy water and balloons.

To perform the rusty roller coaster, both women undress and one end of the rusty pipe is inserted into the anus one one of them. The second woman pours the soapy water into the rusty pipe to fill up the anus.

A balloon is placed over the open end of the rusty pipe and woman #1 carefully stands up to drain herself of the liquid through the pipe e.g.. rusty roller coaster into the balloon. The balloon is tied shut and thrown at the head of woman #2.
Sheila really gave Jessica the rusty roller coaster last night, she showered for an hour to get clean.
