Another term for kissing, because fettuccine noodles are long and flat like tongues.

First used in Supergirl #19, when Supergirl and Wonder Girl were about to Kiss (we're not joking. seriously, look it up) and Ravager (who is apparently the lesbian equivalent of a cockblocker) interrupted them (with a rocket launcher) and said the bellow sentence.
"Wonder-Girl AND Supergirl scraping fettuccine alfredo? Someone get a video camera... we'll get two billion hits on YouTube."
