laundry
Laundry can and is often used as a code name for sex, for discussion around people in public, or for people who are uncomfortable with the term "having sex" or "intercourse."
Example:
A woman says to her husband "Can we do the laundry?" The man says to his wife, "I already did the laundry, it was a small load, so I did it by hand."
