Mental Floss has a list of the 31 "most adorable" terms for sexual intercourse from the last 600 years, complied from the massive Green’s Dictionary of Slang. Some make sense, others are cryptic, at least to me. "Give someone a green gown." Huh?
[UPDATE: In the comments, PGT explains the "green gown" term: "'Give someone a green gown' is actually one of the better known ones — it refers to acquiring grass stains on one's undergarments from vigorous exercise while lying in the grass. 'She has a green petticoat' was Victorian for 'she's a slut,' and even into the 20th century green woman's underwear remained unpopular."]
