There are those who may be addicted to that love "high." They need that amphetamine-like rush of dopamine, norepinephrine and phenylethylamine. Because the body builds up a tolerance to these chemicals, it begins to take more and more to give love junkies that high. They go through relationship after relationship to get their fix.

Jennifer is a lovejunkie. After she broke up with Sean, she got with Gage as soon as possible.
Someone who NEEDS to be in a relationship as much as an addict NEEDS their crack, heroin, or whatever else. As soon as one relationship starts do go downhill or ends, the love junkie will quickly have someone else lined up so they're not single for longer than a few weeks. They have little to no identity outside whoever they're with, and as quickly as they attached to you, they detach and find their next fix.
My ex was such a lovejunkie, we got together 2 weeks after she broke up with Tina, and when we started having problems she started romancing her online friend in NC who she left me for at the end.
While our lifespan is the number of years we will live, our healthspan is the number of healthy years we will have and our sexspan is is the number of years we will continue to be healthy enough to continue having an active sex life.
A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
