The desire to hook up sexually with someone you haven't seen or heard from in many years. Can also refer to the actual sex act with said person or persons from your past.

Comes from the name of a warm and fuzzy nostalgia series that used to air on VH-1; you don't actually need to have been alive in the 80's to drop this phrase.
Dean: Dude, you'll never guess who I got a random message from on Facebook last night! Sarah, from Mrs. Russell's Home Ec class, remember her? You should see her now, she's smoking hot!

Gene: No shit? What's up? She trying to remember the 80's, or what?

Dean: Oh yeah buddy, I'm totally meeting up with her tonight and I am gonna knock that shit OUT!

Gene: Word son! Get me some stealth pics!
