The act of two users pretending to have a (virtual) relationship on an online forum, to add some drama to the forum.
They post dirty talk on each others profile pages, have avatars with the other persons name in it, express their love for their partner in their signatures and heavily quote each others posts. Having a LOT-relation can quickly make both users known at the forum and is generally a source of amusement aswell.
A partner may find himself heavily frustrated upon seeing a new name in their now ex-lover's signature or avatar, indicating that he/she has a new LOT-buddy. This oftens happens when the unlucky user has been inactive or was just boring the shit out of his/her partner. LOT-breakups spawn more drama at the forum, adding up to the fun of having such a relationship.
