A person that, due to riskysexual behaviour, have more STDs than your local streetwalker
"... if the girl keeps insinsting on fucking without a condom you can assume she fucked a lot of guys who wouldn't use condoms in the first place. You'd basically fuck a stdclopedia" - random dude in 9gag
A term used as a way to describe a song that consists of sexually-explicit lyrics, typically to a degree where mentions or depictions of sex are constantly sung in the song. Some examples include:
"Make U Cum" by Ayesha Erotica
"Girls" by The Dare
"WAP (feat. Megan Thee Stallion)" by Cardi B
Person 1: "Did you hear that new single from The Dare?"
Person 2: "That song is so STDcore."
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.
