"pic for pic?" basically means the person who asked the question wants to swap nudes like a boy sends a picture of his penis and in return gets a picture of the girls breasts and vagina or it could even be just one of the two. (preferably over snapchat so you know if the person has saved them)
boy "pic for pic?"
girl "yeah sure!"
(-(girl sends nude, boy sends nude back)-)
boy "thanks!"
girl "no problem!"
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.
