Someone who is completely naive or innocent who you could never picture doing anything sexual. Usually refers to males. Not based on physical appearance.
"He's SUCH a babypenguin!!!"
"I know! Girls are too sexual for him..."
Someone who you cannot picture in a sexual way whatsoever (to the point you reject the existence of their genitalia), it could also mean someone who is avoids anything sexual and becomes overly uncomfortable and awkward if anything related to sex comes up.
"We were making sexual innuendos all night but he didn't get any of them..."
"Probs because he doesn't know what sex is...he's such a baby penguin!"
or
"He always leaves the room if the word sex even enters a conversation...typical Baby Penguin..."
"Well, he probably doesn't even know what a vagina looks like..."

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.
