"Sexual Predator Dave", This is the nickname for a/any "large" person with particularly bad teeth and an all-around gross appearance named David that has a liking for underage girls. The girl of choice is usually around 12 years old.

Hey did you see S.P.D. today over at the pre-school? Because he wasnt at his house, or the elementary school, or the middle school. I sure hope i can get a hold of him before he gets a hold of another little girl.

S.P.D.F 

An acronym to remember the order of subshells in an atom. The first subshell is the S subshell, then the P subshell and so fourth.
To remember the acronym, think "Stephen Porks Dead Ferrets" (the name stephen can be replaced with any name starting with 's') provided they are a weiner you know!

Remember the order of subshells kids, use S.P.D.F, Stephen Porks Dead Ferrets

S.L.P.D. 

S.L.P.D. stands for 'Sweet Lincoln Park Dude', which refers to type of male you may commonly find in the famous upscale neighborhood of Lincoln Park in Chicago, IL. They are usually found wearing collared shirts, North Face apparrel, or designer t-shirts. SLPDs are also usually found in large groups at overpopulated bars/clubs drinking Heineken or overpriced liquor. They are always judging themselves (and others) on where they are, how they look, or how much sexual activity they can engage in.

"You want to go to that club?! Do you realize how many S.L.P.D.s will be there?!"

"Wow, maybe I should pop my collar so I can fit in with all the S.L.P.D.s here."
