Frottage is French, but it's still a pretty good word.
As a consensual activity, it is lauded for its safety. In its seedier sense, frottage seems to be correlated with the use of public transit. The Tokyo Regional Rail system is particularly notorious. Spunk is a quality famously attributed to Mary Richards by Mr. Grant, as well as the substance most frequently felched. Spooge is spunk, or the act of expelling same.
