Lando, as in Lando Calrissian from the original Star Wars Trilogy. You use the name, or "word" in this case, as an adjective to describe something that is hip, funky, smooth, just like Lando. The use of "Lando" in a phrase was first coined by Mark, of Classic Game Room HD, the video game review channel on youtube, in his review of the Star Wars Arcade game for the Sega 32X when he said "I'm going to use a Star Wars name as an adjective to describe this. Star Wars Arcade is 'Lando'."
