What is a throuple?

A romantic relationship between three people

A throuple is a romantic relationship that involves three people, instead of the more traditional two-person couple. The name comes from the combination of "Three" and "Couple."

The term gained traction online in the mid-2010s as a way to refer to a polyamorous relationship between three committed people. This "progressive" relationship consists of three people who are consensually committed to each other. It is unlike a "Threesome" (3sum), which is a term often used for a sexual encounter between three people that does not include any commitment. It may also be spelled as "Thruple."
