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."
