When you sleep with the original person that you lost your virginity to many years after having several other partners. This is in reference to the movie Looper.
Looper: Dude I had sex with my high school sweetheart the other day. I haven't hooked up with her in 6 years!!!
Friend: Wow man! don't you think you're a little young to be closing the loop?

After hours of diligent stretching I was finally successful in closing the loop, then my mom walked in.

An intimate relationship of common understanding and agreement among three individuals, usually where two persons are married or similarly bound; where individuals may be heterosexual, homosexual, or bisexual; and, where all individuals remain faithful and exclusive to each other.
Unlike a ménage à trois, a closed loop relationship ("clr") is typically a long-term relationship that involves a third individual as a functioning, participating partner. Also unlike a ménage à trois, intimacy is not the sole motivation and serves as complement to the relationship. Individuals in a clr may live together, though this is not typical. At the fringes of a clr is the situation where one participant is a committed participant in another relationship, such as being married.
