The name of a song performed by Rick Sanchez and Morty Smith in attempt to show "what earth has got," to please the Giant head (Cromulons native to the Signus-5 expanse), so that it can stop climate change and go away.
Getting Schwifty appears to be made up by Rick Sanchez but is believed to involve taking off your paints or panties and shitting on the floor.
To get truly Schwifty, it’s not just taking off your pants and your panties, and shitting on the floor. It’s also getting high, drunk, and fucked at the same time. Whenever your at a party you just want to get Schwifty to have the best fucking time of your life. When your Schwifty your alway so horny and crossed. You haven’t lived unless you’ve gotten Schwifty.
Morty: “Hey Rick can you teach me how to get Schwifty?”
Rick: “ (drunken burp) Morty if you want to get Schwifty you need to stop being such a fucking pussy and learn to party.”
To 'get schwifty' is the verb form of MacGyver. To MacGyver is 'to make or repair (an object) in an improvised or inventive way, making use of whatever items are at hand'.
Rick tells Morty to "just hit a button, give me a beat" and then proceeds to make up a song on the spot. Rick being the filthy old man that he is uses the first lyrics that come into his head, "take off your panties", "shit on the floor". These are not what it means to get schwifty.
