Two Dogs Friends

• Frenemy: A portmanteau of the words fr(iend) and enemy, the term frenemy refers to someone who pretends to be a friend but actually is an enemy—a proverbial wolf in sheep's clothing in the world of friendships. This is also known as a love–hate relationship. Most people have encountered a frenemy at one time or another in the same places one might find friends—school, work, the neighborhood. The term frenemy was reportedly coined by a sister of author and journalist Jessica Mitford in 1977, and popularized more than twenty years later on the third season of Sex and the City. While most research on friendship and health has focused on the positive relationship between the two, a frenemy is a potential source of irritation and stress. One study by psychologist Dr. Julianne Holt-Lunstad found that unpredictable love–hate relationships characterized by ambivalence can lead to elevations in blood pressure. In a previous study, the same researcher found that blood pressure is higher around friends for whom they have mixed feelings than it is when they're around people whom they clearly dislike.
• Fruit flies, fag hag (female), or fag stag (male): denotes a person (usually heterosexual) who forms deep ties or close friendships with gay men. Men (gay or straight) who have lesbian friends have been referred to as lezbros or lesbros. The term has often been claimed by these straight members in gay-straight friendships, however some feel that it is derogatory.
• Imaginary friend: a non-physical friend created by a child or even an adult. Sometimes they're human, other times they're animals like the life-size rabbit in the old Jimmy Stewart movie, Harvey. Imaginary friends are also created for people desperate for social interaction but are isolated from contact with humans and pets. It may be seen as bad behavior or even taboo (some religious parents even consider their child to be possessed by an evil "spirit"), but is most commonly regarded as harmless, typical childhood behavior. The friend may or may not be human, and commonly serves a protective purpose.
• Internet relationship: a form of friendship or romance which takes place over the Internet. Some internet friendships evolve into real life friendships. Internet friendships are in similar context to a pen pal. These friendships are also based on the thought that the other person that they may not have ever met in real life knows them for who they are instead of the mask they may use in real life.
