Sweet Nothings is a microgame found in WarioWare: Touched! in the Mic Rocking stage. Its name references an idiom that refers to flirting with someone. There is also a souvenir in the game known as Play By Ear that uses the same art style as this microgame.
The objective is to blow into the other person's ear to sweet-talk. It also has twice the time to complete.
