Throuple

A couple that has a mutual friend or third wheel that is always with them.

Or when a couple’s mutual friend consistently hangs out with them after 6 months or more.

This includes hanging out together on known couple holidays like Valentine’s Day.

Ever since Bob broke up with Kim, he and Ted and Michele have become a serious throuple.
