A Cess Pool is a term used to describe a collection of female acquaintances to be shared as a common resource among a group of guy friends.
To be eligible to be added to the Cess Pool, the female in question has to be of a decent standard, and should not be the love interest of anyone in the group.
The main purpose of adding females into the Cess Pool is to always have a group of female friends ready to be called upon by the group for any activities such as clubbing, drinking or even unadulterated sexual debauchery.
A: I just met a couple of cool girls over the weekend.
B: That's great, just add them to the Cess Pool and we can hang out this weekend!
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.
