Refers to just-minuscule reimbursements/favors here and there dat a chick allows you for your help, and without her even giving you any a** in da bargain.
I agree dat a girl's body is her own, but if she doesn't reimburse you adequately --- or at all --- for requested help and also refuses to spread her legs for you, then it does indeed seem like a "bottomless pittance" deal to me.
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.
