Alot like "lol"... but cooler. Its for when something is funny but you just arent "laughing out loud". Because lets face it "lol" is overused and getting a bit old.

"One last one" used to define that last drink (or whatever) your friends talk you into at the end of a party when you know you shouldn't. Usually used repeatedly during the same occasion. Chronic offenders granted membership in "the OLO Club".
